Bugs (Skyrim)

Bugs and glitches

 * Quest 360: "wait for Brelynn's Spell for expire", She walked around a wall while i was talking to her, so the wall was between us when she cast the "spell", so the spell never landed and affected me, so it cant expire even though the log thinks it did.
 * Game Play:360 : Dead Dragons stoped desolveing and giveing souls. ive 8 unspent souls.
 * Quest 360 the wall for the saphire dragon claw wont open. ive entered the right patern from the claw. even looked it up and tryied all combos. works on the ps3 version so it know its right.
 * Quest 360 " Help Selveni Nethril escape the cave" she walked and got stuck to close to the cave entrance without leaveing. so when you go back in to talk to her, you cant get close enough to speak to her, trying just makes you exit the cave.
 * Quest: 360 "tending the Flame". get all the way down to where the bards body is, and your suposed to pick up the verse, but its not there. the arrow is, but nothing. so you cant go on, cant open the wall for the the claw (coral dragon claw), and you cant complete the quest to gain entry to the bards college.
 * Quest: after completing the quest "good intentions" from the college of winterhold, Savos Aren does not give you the revealing the unseen quest, also talking to Mirabelle Ervine without the quest wont start it. only happens to some players and this is reported on the xbox360.
 * Quest: "waking nightmare" - entered the temple at the same time as Erandur and now he jumped further in the temple with out making the wall disapear so i cannot follow him and cannot complete the quest. (xbox 360)
 * Quest: "Hired Muscle" - npc objective already dead. Can't complete Companions mission as Alvor was previously killed in a random dragon fight earlier in the game. (PS3)
 * Environment: Shadow flicker bug - shadows flicker from the movement of the day/night cycle creating a flashing strobe effect. (xbox 360, pc, and ps3)
 * NPC: Yatul - randomly spawns around, even if you are talking to her she'll just instantly move a little distance away. (PC)
 * Quest:The Throat Of The World - "Talk to Arngeir" Arngeir is stuck outside he doesnt move unless you fight him close up, when you talk to him he says "Come inside, the others wll meet us there"
 * Quest:The Jagged Crown - If you explore Korvanjund and kill the bandits before doing this quest the entrance is blocked.
 * NPC: Sinding - after he becomes a werewolf and escapes, if you do the following quest and spare him, he ends back in the Falkreath Jail, but for no apparent reason. (PC)
 * Quest; Speak to Greta about going to the Temple of Divines: If you have already looted the Amulet of Talos from Roggvir's body after his execution when picking up this quest - when you speak to Greta about going to Temple, she will give her completion speech but the quest will not complete. You recieve no reward and the Amulet stays in your inventory. This also seems to happen if you are already in posession of an Amulet of Talos when you loot the Amulet from Roggvir.
 * NPC : Critters: I have noticed in exploring Skyrim that occasionally rabbits will be hopping along underwater in the middle of a lake. Likewise i have been chased out of a pond and for a good long ways across land by an overachieving slaughterfish. (PC)
 * Quest: Season Unending: Ulfric Stormcloak will not talk to you if you are also on Joining the Stormcloaks. Additionally, if you have already spoken to General Tulius and had him agree to meet at High Hrothgar, Galmar Stone-Fist will no longer speak with you, preventing both quest lines from moving forward. (PC AND XBOX)
 * Quest: When you talk to the Jarl of Whiterun to capture a dragon in the palace, he stops you from ending conosations, stoping you from progressing though the story, side quests and buying or selling items. (PS3 and only sometimes).
 * Quest: Revealing The Unseen: After you have found the ruins of Mzulft when you go in the first doors Gavras Pinius will not speak to you, die and you are unable to pickpocket him.He just talks saying normal NPC lines.
 * Quest; Trinity Restored: If you wait too long to meet Karliah at the standing stone she disappears, and Brynjolf returns to the Ragged Flagon.
 * Quest item/Quest; Find Books for Urag: At the library of the College of Winterhold, you get miscellaneous objectives from Urag in the Arcaneum to find Books. Problem is, the books are available from the very beginning of the game (even in a boss/end chest, making them easily picked up by players), and is tagged as quest items (therefore, unable to be dropped). Furthermore if you accidentally pick them up before getting the quest, the quest won't update even though you already have it in your inventory. There's NO way to drop the books and pick them up again to update your quest, resulting in a quest never being completeable and a 1 lb book stuck in your inventory forever.
 * Quest item/Quest; Arondil's Journals: While attempting to turn in the journals to Vekel the Man in the Thieves Guild, the quest does not finish correctly. Vekel will give his completion speech, but you will earn no reward, and the journals will still be in your inventory.
 * Hjerim: If you buy Hjerim, sometimes happens that the steward of Windhelm does not offer the "Clean up the murders mess (500)" in the decoration menu. To see the effect of the bug see this for reference.
 * Cache: Having a savefile that's larger than 5.5 mb can cause your game to lag. (This is a PS3-bug only) Confirmed.
 * Animation: When smithing piece of metal is held with the red hot end pointing in the wrong direction and the metal becomes stuck to your arm until you stop blacksmithing. Confirmed for PC, XBOX, and PS3.
 * Companion: When you enter the maze at the labyrintian if your follower is lydia she might get stuck in the maze just past where you enter and will be unable to leave the maze. She will continue to follow you into the maze for only a short time, after you reach a certain point the she will step back and stop following you. At this point she wont leave through the entrance or follow you to the exit and will become stuck forever. This is also true of other followers (Confirmed on XBOX and PC and PS3.)


 * Nightingale: After finishing the thieves guild quest, if you return to the Twilight Sepulcher Inner Sanctuary after completing the Dark Brotherhood quest line, there is no longer a way to change your Nightingale ability. The room is completely different and only the one pad that you stood on to get whatever ability you have is still there.
 * Armor: Dragon Armor and Daedric Armor have the same quality. (PC)


 * Quest: The Forsworn Conspiracy (PS3 and PC); while Eltry asks you to investigate around Markarth, he mentions to check in with him after you find out who was behind the recent murder. If you do not check in with Eltry after EACH clue you find (you have the opportunity to find them all from the start), upon return to Eltry's (when prompted to) he is found dead on the Alter of Talos, where a guard now stands where he once was; meanwhile the indicator arrow to "talk to Eltry's" is still hovering where he should be. At this point the quest is uncompleteable. Note: Depending on the choices you make, Eltry's is SUPPOSED to die, however in this scenario the quest is supposed to expand to the guards arresting you at the shrine.


 * Quest: Find Hrolfdir's Shield for Igmund (PS3)--Numerous reports of clearing out the Hag/Forsworn building to find nothing in the marked chest (where the shield should be located). The quest is then not able to be completed.

Can be fixed by changing the editing tab section. (PC) open the console Type "setstage MQ202 160" He will open his door, speak to him to advance the quest, eventually leading to escorting him to Riverwood. When he gets there, let him speak to Delphene. She will lead you back to her hideout and the quest scripts should activate on their own.
 * Quest; House of Horrors: In the mission House of Horrors the door locking sequence was reversed so i was free to leave during the screen fading and Daedra worshipping moments but after i had used the Alter the door to the outside locked me in. When i went back through my autosaves and tried to just leave the house, no matter what i did i couldn't make the screen effects go away.
 * Perk: The 'Bribery' perk star in Speech constellation may not light up during point assignment.
 * Companion: When entering Black-Briar Lodge, speaking with Lydia (If she is set as your companion) will result in her saying "Youre not supposed to be in here!" angrily and her dialogue box will not appear.
 * Quest: In the Revealing the Unseen Quest for the College of Winterhold, on the Focus the Oculory objective if you exit the dwarven ruins and re-enter - possibly turn off and resume game - Frostbite and Flames no longer have an effect on the focusing of the light.
 * Quest: Disrupting the Skooma Trade/ Riften Quest - If you have already cleared out Cragslane Cavern before starting the quest, you cannot finish the quest. (PC)
 * Quest: Kolskeger Mine stays full of "Foresworn" after completeing the quest and clearing out the mine (PC)
 * Shout/Effects: Elemental Fury can cause left handed weapons to swing in super slow motion when not affected by the shout. Can stop the swing by sheathing the weapons or switching to a spell. Both weapons will swing at the appropriate speed as the shout is affecting the player, once the shout ends, the weapon will swing extremely slow agian. Only occurs when dual wielding two weapons. Single left hand weapons swing normal, and fists swing normal as well. (Can effect the right hand instead of the left hand as well.) This bug is rumored to be fixed by getting an enemy (Draugr) to Disarm Shout at you. NOT confirmed.
 * Shout/Effects: After shouting Elemental Fury, there is a chance that the heavy wind sound won't stop after the shout ends and keep sounding forever, no matter what you do (quit and reload, fast-travel, use Elemental Fury again nor a different shout...). This also can happen with the Chillrend weapon and other Shouts, the sounds keep repeating just like the Elemental Fury bug. Might be the same problem. (Video Demonstration ) This bug is rumored to be fixed by getting an enemy (Draugr) to Disarm Shout at you. NOT confirmed.
 * Bound Spell: Casting the Bound Bow spell and immediately crouching (before the summoning animation completes) causes your weapon to be permanently sheathed. The only recourse is to reload an older save (the bug persists even after changing weapons/magicka).
 * Quest: Glory of the Dead will not begin after completing Purity of Revenge quest (Xbox 360, PS3)
 * Companions questline: If you have already cleared Driftshade Refuge beforehand, at the completion of 'Blood's Honor' for the Companions, the game offers you no dialogue choice to accept the following quest; essentially breaking the progression of the Companions quest line until fixed. (PC, 360, PS3). Note that some reports will say that such and such misc. quest sent them to Driftshade Refuge, but it's the actual killing of all bandits in the location (resulting in it being marked as "Cleared") that triggers the bug.
 * Environment: In the Riften Prison the wall dissapears incredibly often.
 * Companion: If a Companion gets caught in a swinging door trap in Bleak Falls Barrow at a low level, they can go through the wall, never to return. (360, PS3)
 * Perk/Effect; Infinite slow time: Sometimes when being attacked by 2 or more enemies when you have the slow time block perk you will enter a state of perpetual slow motion. This will allow you to easily dispatch pretty much all enemies with ease. This effect will persist through changing zone or reloading and can make mundane tasks ,such as unbarring doors and reading books, painfully time consuming. To remove this infinite slow time you have to enter combat and block another power melee and it should drop naturally. You can also wait to remove the infinite slow.
 * Animation/Alduin: In the first fight with Alduin he may look like he's standing in midair while shooting fire at you and dragonrend won't affect him ( NOTE: Alduin being unaffected by dragonrend is intended - there is a global variable that sets whether or not he's affected by it, so leading to obvious intention.)
 * Quest; Blade in the Dark: Cannot complete blade in the dark when the dragon shouts and the other dragon comes out of the burial this does not happen instead he just keeps shouting
 * Loot/Dupe: Items looted from a corpse that have a world model and fall from the NPCs upon death (e.g. weapons and shields) will sometimes not despawn the world model when the item itself has been looted from the corpse's inventory, allowing players to pick up the world model and obtain a duplicated item.
 * Quest/NPC: In companions quest when you are supposed to give aela her shield you will be given a marker near a giant/mammoth camp and she will be nowhere around and completely vanished from the game making the quest impossible. While outside Whiterun, there is a quest indicator on the city gate, showing she is in the city, but she is not. She never goes to her bed in the basement of Jorrvaskr. (360, PS3)
 * Shout/Graphical: Second word of power for Clear Sky's shout won't update. Either disappears when you get close or will flash in and out. (possibly related to flashing graphics bug, possibly happens shortly after reaching lvl 13) PS3.
 * Quest; Stromcloaks Storyline: The quests "Joing The Stormcloaks" & "Season Unending" stop me from talking to Ulfric, he says you have to complete "Joing The Stormcloaks" but you can't talk to Galmar either, he says a piece of dialog relating to "Season Unending" - comfirmed for PS3
 * Quest; Blood in the Snow: After finding both journal entries and investigating the house during "Blood in the Snow", you may be unable to talk to the Jarl's assistant, despite the quest description directing you to him.
 * Quest; Blindsighted: In the thieves guild quest Blindsighted the cutscene with Mercer always makes him get stuck on a rock or something and the movie clip will never end. I fixed this by pausing a'nd unpausing'.
 * After defeating Mercer and the room fills with water Karliah will walk around under water before disappearing into the ceiling, making the quest uncompletable.(360)
 * Quest; Under Saarthal: In the Under Saarthal quest, Collect the four artifacts able to collect the first 2 but gate is up preventing from picking up the other two including the necklace that allows the gate to be moved. (PS3/PC).

 * Graphics: Boots of the Old Gods have a different model than previewed (with transparent ankles)
 * Graphics: Helmet of the Old Gods has a different model than previewed.
 * Quest; House of Horrors: 'House of Horrors' Bug - On entering the Abandoned House for the quest, the Justicar does nothing, in order to continue the mission you must kill him, after continuing to the Daedric altar and after the ensuing dialog, you are unable to leave the house. (Confirmed on Xbox 360)
 * Quest; Reveal the Unseen: Dwarven Armillary Quest Orb cannot be expanded/shrunk with Frostbite or Flames. People have to revert back to a previous save game before placing the orb in the armillary before continuing. (Confirmed on PC, Xbox 360, and PS3) ( Video Demonstration )
 * Dual Wield: Improved weapons of the same variety (ie. Orcish Sword Superior, Fine Steel War Axe) cannot be dual wielded through hotkeys or on the favorites menu. They will also unbind the key. (Confirmed on Xbox 360 and PC)
 * Quest/NPC/Riften: After placing the ring in pocket successfully unable to speak with Brynjolf in Red Flaggon succesfully to join the thieves guild. The game continues as if he is still giving his speech in the marketplace. This also means no traders in the marketplace can be traded with as all act as if not at their stall. [This is caused by starting the quest at night, it allows you to complete but Brynjolf doesn't move on talk:Bugs] (Xbox 360 and PC)
 * Animation?: If you jump into water with a horse the horse will swim, if you get off and get on the horse again then you will ride as you do on land. (please improve this)
 * Quest; The Way of the Voice: After you've been told to use your shout ability by Arngeir, the objective "Speak to Arngeir" remains uncompleted (PS3, PC) (Unconfirmed: 360).
 * Quest; The way of the voice: After you learn the word of power form Einarh, your suppose to shout at the "targets". But theres an occourring bug that prevents that. When one of the Grey Beards goes to summon the "target" it has the summing animation but the "target" does not appear, there for impossible to complete the mission. (XBOX 360, PS3) (Unconfirmed: PC)
 * Quest Item: When quests begin and there are quest specific items suchs as the litter around Diabellas chapel in "A Night to Remember" you cannot drop these items until the quest has ended. For example, the priestess asks you to pick up your mess, if you bribe her instead of cleaning, you can still pick up the items however those items will be considered 'quest' items until the ENTIRE quest line is completed, not just that section. Confirmed 360.
 * Quest; Glory of the Dead: During mission, game gets stuck if Euorland doesn't attend the funeral and therefore cannot re-make the companions weapon.
 * Quest; The Forsworn Conspiracy: During the quest, if you restart due to a fail and do not read the note to find "N" before you kill Nepos, you will return to The Talos to find the quest giver to have died and nobody will pin the crime on you or anything, leaving the quest unfinishable.
 * This quest also appears to bug after you kill Nepos and go to find Eltrys, the imperial legion Guard will not arrest you. Instead he talks about joining the Legion and the other guards are equally unhelpful leaving the quest unfinishable.(PC)
 * Item/Object Interaction: Weapon racks and wall plaques may not work. (360,PS3)
 * Item/Object Interaction : For some reason at some point you can't interact with objects anymore ( arcane enchanter, alch labs, mine ores, chairs etc). When you click "use" your character only briefly freezes and after that nothing happens. (PC, PS3)
 * Marriage; Lydia: For some reason you can't marry Lydia' even when you have the Amulet of Mara. And it has been confirmed on the skyrim marriage guide that you can marry her. Website - http://www.gamefront.com/skyrim-marriage-guide/ (PC/Xbox360/PS3)
 * Skilltree: Skills will be shown in red on the skills screen and will be shown as being lower than what they actually are, even when not currently afflicted with any debuffs (confirmed on active effects screen). [PC/PS3]
 * Missing Animation: Not really a bug but when sheathing dual weapons the second weapon just disappears (i.e. Sword, War Axe). Animation for 2 sheathed weapons (either side) when dual wealding needed. [PC]
 * Enchanting/Values: As you improve your enchantment skill, the value of the same item with the same soul & enchantment goes down rather than up. (work around Xbox 360, drop the item, and pick it back up, try it again.)
 * NPC,Shadowmere: If Shadowmere is knocked down in water, she will not come back at a later time, or ever. (confirmed PS3)
 * Quest; A Cornered Rat: During the quest, the sound of the dialogue while talking to Esbern does not play and the door to his hideout cannot be opened, making the quest unfinishable. On PC platform, you can enter the Console (default key is the top left key, just under esc.) and write "tcl" to toggle collision off, enter the room and then toggle collision on again with "tcl".
 * I was able to make the door open on the PC version by trying a few times and then zoning back out to the previous area and backn in immediately. the door to his room was open when I returned. The speech sound bug persists though.
 * Sometimes Esbern just stands in his room by the chest, refusing to move. You have to press "E" a few times quickly, and then you will be able to speak with him, asking him, if he knows a way out.
 * Method 3: finish dialogue, go back to the rat cavern, enter the door, then go back. by then it should have opened.
 * Zoning/Dark Brotherhood Sanctuary: Sometimes when zoning into the Dark Brotherhood Sanctuary character will continue to rezone randomly inside the Sanctuary, Re-zoning fixes this.Sometimes zoning animation happens more frequently after each intial rezone caused by the bug. (PC, 360,PS3 uncomfirmed)
 * Camera?: 1st person camera bounces off NPC's when face-to-face or preforming and close up attack. Example: 1st person crosshair when on the enviroment acts normally however when moving the camera to have crosshair on npc the cross hair bounces off when it hits the body.
 * Graphical/Item Model Error: When wearing the Dragonplate Helmet (Legendary quality) as nord female, the hair can be seen through the helmet model. It is uncertain if this applies for the normal version or other races/males aswell (PC). This does not happen with male (Nord) characters (360).
 * Alduin/NPC/Broken Quest: After you kill Alduin, Paarthurnax becomes unkillable, making The Blades' quest Paarthurnax unbeatable, but this allows you to train any target based skill forever, as he will not fight back.
 * Companion Inventory Bug: Upon entering combat, companions/followers revert back to using their default weapon/armor with better equipments in their possession, this happens if you dismiss them and rejoin later; may be resolved by trading any item with them. (PC, Xbox360)
 * This also happens whenever you take companion with you, edit their inventory (giving them new/better gear), then tell them to part ways. The next time you see them they have their original gear on. As stated above, easily fixed by editing their inventory again, though it is somewhat annoying at times being a time-consuming process.
 * Shroud Hearth/Sapphire Claw: The door that is opened using the Sapphire Claw will not open, even with the correct combination. Instead, one or two of the dart traps go off. (Xbox360)
 * Quest; To Kill an Empire: (Dark Brotherhood) After you give the Note to Commander Mara and continue to the kitchens, when you talk to Griena she will loop the dialogue and not finish it resulting in never progressing in the quest. Since the door is locked to get back to solitude you are stuck in the kitchens with a quest line that doesnt work. (Xbox360)
 * Graphical/Stuck Arrows: A constant reocurring problem seems to be when your shot by an arrow or any form of magic that causes someting to "stick" to you, the item wont go away. (the arrow stays in you forever) but can sometimes be solved by getting shot by an arrow, causing them both to dissapear. Solution confirmed 360. Also it seems to fix itself as you continiue playing.
 * House Upgrades: After purchasing the bedroom upgrade for your the House of Whiterun, they [?] no longer sort alphabetically, instead sorting by either weight or random. more specific please.
 * Remapping Keys: Remapping left mouse "M1" to something else is impossible because as soon as you assign it, it triggers a left click therefore requiring you again to enter a new key. (PC)
 * By default, left mouse button is assigned to right hand and right mouse button is assigned to left hand. how is this a bug? (PC)
 * Remapping Keys: Each time the game restarts, all changes you have made in control keys goes back to default. (PC)
 * Fix: Run as administrator.
 * Lock Bug: Volunruud cannot open locked door even when the two weapon keys are obtained
 * Character Creation: when you first choose your race and appareance, left clicking your 3d image to rotate it will disable the left click for any other actions such as changing parameters.
 * Physics: Dropping items will sometimes damage yourself if the object physics touches you.' This is not a bug, merely unlucky positioning of character. Happens rarely.
 * Equipping Spells: Impossible to un-equip or change spells on the right hand. To fix it, one must equip a weapon to this hand. (PC)
 * Physics: Getting frozen on a cliff may result in physics glitches. Video exemple : http://www.youtube.com/watch?v=F5-kO_iIzhU (PC)
 * Remmaping keys : Remapping "Weapon Ready/Holster Key" ('R' by default) causes the 'Drop Equipment' key in the inventory menu to also be remapped, even though it says to press 'R' to Drop. Interestingly, the 'Store Equipment' key when inspecting chests (also 'R' by default) isn't erroneously remapped.(PC)
 * Quest, Attack on Whiterun : When attacking Whiterun during the "Attack on Whiterun" quest, with the Stormcloak. Galmar starts attacking you after you get inside the gates of Whiterun.(PS3)
 * Chest, storage, items : Not sure if this is a bug or just left out, but chests and storage containers do not sort items at all. I.E. a Chest will not have the 'weapon' 'apparel' 'potions' sub category. Also the chest will not sort these items by alphebetical order either. It seems that it sorts them by the order you place them in the chest, Makes it very time consuming to hunt down a particular item in the chest.
 * Minimizing : After the game has been minimized, it is impossible to go back.(PC)
 * It is possible, after using Alt+Tab the screen will be black, use Alt+Tab into the game again and it will enter, just remember you have to do it twice and it will work. (This fix doesn't work for everybody.)
 * NPC dialogues : Multiple NPC can talk to you at the same time making it impossible to understand any conversation. Sometimes this will interrput important quest conversations as well.
 * NPC : Some NPC will rotate while sleeping Video example : http://www.youtube.com/watch?v=bZyj38AImNI
 * Physics : When attempting to put scimitars on a weapon display, it places one curving upwards and one curving downwards making it looks uterly stupid.
 * Quest, quest name? : When equipping the Ring of Hircine (after completing the quest) the "reading the elder scroll" animation sometimes displays. (PS3)
 * Enemy Spawning : Mammoths and goats floating on a tree, then falling down to the ground without dying.
 * During the quest (The Fallen) after traping the dragon no more options are available. Killing the dragon only causes him to spasm and repeat the cycle over and over.
 * Quest, name of the quest = ? : When using the Elder Scroll to go back in time and watch the fight with Alduin, the NPC's say "Alduin is coming, get ready!" or something along those lines, and only 2 stand ready, the younger male is further away looking at the distance and not coming to fight, Alduin will never come, re-loading the save and using the Elder Scroll again fixes it. (PC)
 * Equipping Spells : You can't dual cast (at least from the favorites menu) by clicking on a spell, it will be either Left or nothing, the other mouse button won't do anything, to dualcast you have to number a spell, and then double clicking the number, but then it will be LR or just R, you can't un-equip a spell except by overwriting it with a weapon. (PC)
 * This may not be a bug - I can in fact assign spells to the 2nd hand from the favorites menu but only if that hand doesn't already have a weapon (at least for me ) (PC)
 * This is a well known glitch, to fix it one must over-ride the spell with a weapon to un-equip it.
 * NPC, follower : After a follower is ordered to take everything from a container, the items cannot be sold even if they are not stolen goods.(PC)
 * Quest, name of the quest = ? : Cursed ring of hircine go off after random transformation (PS3)
 * (PC/XBOX) Completing the quest Diplomatic Immunity does not always give you the quest A Cornered Rat, and there is no way to go back and pick it up. Causes the main questline to be unplayable, as this is a required quest. If you are on a PC, you can fix this using the console:
 * Go to Riften and wait right outside Esbern's hideout in the Ratway
 * Spells/perks : Augmented Flames/Frost/Shock perks do not increase the damage of Flame/Frost/Lightning Cloak spells.(PC)
 * Quest, "The Man Who Cried Wolf ": After accepting the quest "The Man Who Cried Wolf" from Falk Firebeard you are able to pickpocket "Letter from Falk Firebeard" from him, which clearly is not supposed to be there until after the quest is done as it describes some of the deeds you did while on the quest.(XBOX)
 * Character : Upon starting a new game and choosing to play as a Nord, the racial ability "resist frost +50%" does not activate and will not show up under 'active effects'. Battlecry will still appear as normal. (PS3)
 * Werewolf : Becoming a werewolf does not give you immunity to disease as stated. (PC)
 * Werewolf : If you become a werewolf and then get the cure changing you back to normal, you still can't become a vampire because the werewolf perk giving you immunity too all disease is bugged.
 * Physics : When a dragon is killed, its remaining skeleton is not a solid object. One can walk trough it.
 * Shouts, swimming : If you try to shout while swimming it will not work but as soon as you touch earth, your caracter will shout.
 * Horse, swimming : If you dismount your horse while in water and then try to mount it back, the horse will be walking on water.
 * Realism : Walking on snow doesn't leave foot traces.
 * NPC, selling : Sometimes, If you try to sell items to those random NPC hunters wandering in the wild, you will not receive the money even if they have plenty.
 * NPC, realism : Even if NPCs have witnessed a dragon being killed by you, they will still say random quotes such as "do dragons really exist?" .
 * NPC,Jarl of Markarth quests: The Jarl of Markarth offers no work or quests making it impossible to become thane or purchase a house in Markarth. (Soluition: must be lvl 20, and have completed any bounty quests for the steward, to get the quests/topics involving house purchase. (PC)
 * NPC, Jarl of Dawnstar quests: The Jarl of Dawnstar offers quests and rewards you with gold when they are complete but no quest completed text comes up and the quests are still in the journal as not being complete meaning you cannot become Thane of Dawnstar. (PC, Xbox 360)
 * NPC, animation : Sometimes NPCs reanimate, walking backwards, after death, see http://www.youtube.com/watch?v=dm9VE04M7j8
 * Quests : If you dont follow the expected path to get to a quest objective, the quest marker might not be refreshed until you have gotten to the objective. For example, lets say that you are on top of a tower and the only way out is by entering a door or by jumping down (while being ethereal), the programmers of skyrim did not predicted that one might jump down the tower so the quest marker will still be pointing to the door even if you are already down the tower. ( all platform, original release )
 * Quest items : Finn's Lute, Pantea's Flute and Rjorn's Drum are bugged as they arnt removed from the inventory once their quests are complete. If Finn's Lute is found before the quest is activated then you can still get the reward for recovering it but it isnt removed from the inventory and the quest is still in the Miscellaneous quest log thus being unfinishable. all the quests are found at the bard collage.(PS3, XBOX 360)
 * (PS3) Sometimes when you equip arrows and then you sell them to any vendor the arrows will still be equiped on your characters back. (Solution) This can be fixed by buying or looting the same sort of arrows back and then un-equip them before you sell them.*Campfires do not hurt you.
 * Sometimes, when picking up items off a table or shelf, all other items on that surface will immediately vanish.*If you are outside, raindrops fall through objects, like roofs etc.
 * (PC) If the player remaps the Sheathe function to a mouse shoulder button, menu functions that require the R key (dropping, crafting, etc.) become impossible.
 * (PC) If Use/Activate action is mapped to mouse key (M4 e.g.) then it's not possible to pickup books, notes and letters. If action is mapped to some other keyboard key picking up works fine.
 * (PC) Unable to unequip swap magic on right hand without dual wielding and removing weapons beforehand
 * (PC) Opening the Steam overlay in menus has a tendency to break the Tab key and act as if Shift is permanently pressed for the current play session, making certain menus impossible to close. (Fixable by pressing the corresponding stuck key once when back in-game.)
 * Skyrim_bug_Morokei_mask.jpg makes head of player character invisible.]]Morokei mask deletes face textures (but only with specific robes equiped. Works with Necromancer robes, not with Arch Mage robes).*
 * In Bleakfalls Burrow, sometimes the stones (bird, snake, whale) for the first lever puzzle wont turn, loading fixed once, but died, forgot to save, now even loading wont fix it. Exiting the cave and re-entering sometimes works to fix this.
 * One time, I must have spawned strangley because my compain Lydia appeared dead on the floor but I could speak to her and she would appear to be dragging along the floor when she followed me. But the glitch fixed itself when I fast-travelled.
 * (Xbox360) If Lydia dies before you marry someone, her body will arive at the door during the wedding. The only solution I found was to drag Lydia's body downstairs and re-propose marriage.

You can also change your race to your current race, which fixes it as well (Note 2: You can remove the face mask after using SetPlayerRace and your head will become visible again, but putting the mask back on will once again cause the glitch to re-occur).

Exploits
Infinite Magic Glitch

If you have an item which has +Magic upon it you can cast spells until you run out of magic and de-equip it and then equip it again to get the magic from the item.  Vendor Inventory Glitch (PC) 

When browsing a vendor's items it is possible to sell the own vendor's items back to themselves and gain gold and speech skill youself. (Video)

 Easy kill - Mammoths and giants 

You can kill them even if you are level 1. Just exploit their bad AI by turning around a rock while shooting them arrows or spells. They will try to get to you but they are too slow. They will eventualy die.

Another easy method is to lure giants or other large aggressive mobs towards door ways they can't get through. So long as you stay slightly out of their range they'll continue to swing at the door frame, this is especially useful when trying to level mage and archery. You can also get away with a hit and run tactic with melee attacks whilst they are using a power move, but don't get too cocky or you'll easily get one shotted.

 Weapon Duplication Trick 

I found this by accident so your milage may vary. Purchase all upgrades to the house in Whiterun.Enter the house and equip two weapons ( I have only tried this with staves) .Go to the weapon rack and activate the right weapon holder. This should remove the staff from your right hand and place it on the rack. Next activate the left weapon holder. This should now place another staff on the left holder. This new staff is a duplication of the first staff that you loaded. Remove both staffs and repeat.

 Alteration Leveling 

If you have the Telekinesis spell, simply drop an item onto the ground and cast the spell on it to bring the item to yourself. You get a surprising amount of experience towards Alteration every time you cast this spell, making it extremely easy to level up. This spell can be purchased at the College of Winterhold.

Leveling Up Exploit

When the beginning scene is finished you'll follow an Imperial to a small fort where you can continue to follow the Imperial or a Stormcloak (you can follow either for this to work). Whom ever you chose to follow will give you a small tutorial of the game as you escape the turmoil created in the beginning scene. As you go through the tutorial you will come to an under ground cave where you'll be taught how to perform sneak attacks. At this point you'll be asked to either sneak attack a bear or sneak past it. Instead of doing either of these you can enter sneak mode and go behind which ever NPC is giving you the tutorial and attack him over and over again with no consequence since he will not retaliate or die. You can use this to level up your one-handed, sneak, two-handed, destruction, and block skill by using shield bash. I'ts better to get them into a corner because when you hit him he will be pushed forward. This is very useful if you're willing to put the time into it. (Video Demonstration)

 Housing Exploit 

In whiterun when you're given the option to buy the house for 5,000 gold there is a way to get the home and keep all that gold. This proves to be especially useful for lower level players who want a house, but don't want to blow all their cash. So, make sure you talk to the Jarl's attendant who sells it to you when he is near a chest, dresser, or something you can store you gold in. Go through the dialoge, say you wish to purchase it, then once you've pressed A to purchse, quickly press B a couple times to leave this screen and then quickly deposit your money into the chest. This also works for all the upgrades available to the house. He will indicate they'll be in your home next time you arrive, and you'll see the key placed in your inventory but you will keep all the gold.(Video Demonstration)

Bucket Exploit

Npc's cant see any crimes while you put a bucket basket or kettle on their head. (Video Demonstration)

Removing "Stolen" Flag on Items

While standing in front of someone, preferebaly someone you are in good relation with, drop the item in front of them and they will pick up the item and give it to you. This removes the "stolen" flag and it will now be your item.

Trainer Exploit

When training with NPC's you can pickpocket the money you spent training back from them. In doing so you can level pickpocket as well, in most cases gaining enough XP to go to the next level.

Other Method- Some NPC trainers are also availaible followers. This can be achieved once you do a certain quest for that character or another character. Once you get them to be a follower talk to them. There will be an option where you can train with them even though they're your follower. Once you trained with them using your gold trade with them. You will see that they will have your gold. Take it the gold and you'll get training for free.

 Follower Exploit (PS3)

"You get Lydia as a companion after you been chosen as the Dragonborn. Jarl Balgruuf will offer her as your assistant and appoint you as Thane. She is an excellent thief." If you have Lydia follow you to the College of Winterhold (Spell Training) in the beginning...take her into the Hall of Elements with you after gaining your first access to the college. The Hall Of Elements is the first place you will train in the College. If you stay in the Hall of Elements after the training is complete...and you still have Lydia by your side, you can tell her to "Part Ways With You"... If you do this within the Hall of Elements, she will begin attacking the other Magi that you were training with..even the instructor. At this point in time, you have already learned "Healing Hands" to gain entry to the college. Lydia does not die after fighting the Magi in The Hall of Elements..she merely gets "stunned"...that being said, you can cast Healing Hands on her over and over as she continues to attack. This will level your Restoration and your Overall Skill levels quite easily with a little time. Enjoy.

Conjuration Exploit

This one is very simple, all you need is a dead body, I tried it with a dead thief in Rifton. After you get your dead body all you need to do continuously use soul trap on it and you'll get conjuration xp. You can do this for as long as you like

 Restoration Exploit 

You will need two spells for this one, the is the "Healing" spell and the Equilibrium spell. The Equilibrium spell turns your health into Magicka and the Healing spell does the opposite. If you duel weild them then you'll be able to gain Restoration xp, but for some reason not Alteration. You will need to stop Equilibrium every now and then, because it drains more of your health than Healing heals, and since Equilibrium restors magicka and Healing restores health, they almost balance each other out. Not sure if it'll still work if you get the "Regeneration" perk.

Restoration Exploit 2

You will need to dual wield healing and have the birth sign of the Astronarches.Go to the Grey Beard monastry and head to the top of the mountain.At the top, there will be a spot with wind circulating it, run into it and heal youself simultaniously for infinite Restoration Xp. (Video Demonstration)

Magic Leveling Exploit

When you first join The Companions in Whiterun you will have to test your fighting skills on one of the members outside of the house. You can continually use spells on this person and he will not retaliate other than saying "What do you think this is? We don't do battle with magic around here, new blood. Now come at me." (Video Demonstration)*Note be warned this could lead to a bug where Vilkas will not continue with the quest and therfore you can't join The Companions (PS3).

 Speech Leveling and Gold Exploit 

Go to any vendor and browse what they have to sell. For example, click Weapons and look at all the weapons they are selling. With the weapons screen open, move your mouse over the the left menu and scroll down until you find your characters name. Right click and hold the mouse button down on your name as you drag the mouse over into the browse weapon screen, and let go. Now you are browsing the shop owners weapons, but you have your characters name highlighted. Click to buy something, and notice gold gets removed from the shop and added to your gold. The item doesn't disappear, so you can sit there and 'buy' the item over and over again until you've completely depleted the shop of all its money. Even after the shop has run out of money, you can continue to sell that item for 0 gold, over and over again and your speech skill will increase forever and your character will also level along with it. (Video Demonstration)

 Infinite (any) Arrows Exploit 

When you enter the inner sanctum of the Thieves Guild, there will be multiple characters practicing their archery throughout most of the day. Simply walk up to the targets and have your pick at all the arrows they have used. Then just wait for them to shoot more arrows if you are in need.

if you have any arrow you wish to duplicate simply steal there equipped arrows ( need misdirection pickpocket perk) and then equip that character with one of any arrow of your own by placing it on them. They then shoot that 1 arrow continually. If they stop shooting simply wait one hour and they will begin to fire again *works great with deadric arrows ;)

 Easy Leveling of Any Offensive Skill With Shadowmere 

When you acquire Shadowmere through the Dark Brotherhood questline, you'll notice that he's nearly indestructable. You may also notice that no matter what you do to him, he won't turn on you. So as long as you don't bombard him with too much (a constant stream of arrows from a level 30 with 75 in Archery with a fire-enchanted Supple Ancient Nord Bow and Elven arrows does next to nothing), he'll provide an easy on-the-go practice dummy for quickly leveling up.

Easy leveling of the skill "Illusion" with the spell "Muffle"

Purchase the spell "Muffle", equip it and also some Magic regenerating robes. Cast the spell and you should easily get many levels up. Not 100% sure on if it works on all platforms, races and professions.

Easy Illusion leveling

Just find any NPC and continuously cast courage on him/her and you will get easy Illusion xp for it.
