I was told to kill the leader of Redoran's Retreat, which I did in an earlier quest. I received the Companions' quest before the place could respawn and when I went there, he was already dead, rendering the quest incompletable. What do I do? Also, I can't use console commands because I use and Xbox 360.
load a save from before you got that quest. I have had the same issue with Halldir's Cairn, since named NPC's do not respawn with the dungeon (with a few exceptions) it will not be possible to complete the mission without console commands. If you cannot load a save from before the quest was obtained then, sorry to say it, but your companions questline is broken.
You can still use console commands to complete quests, if you are playing on a PC. "completeallobjectives <questid>" will mark all the objectives of a certain quest currently open on the journal as complete. Then, you should check the wikia or uesp to get the appropriate quest stages and use "setstage <questid> <queststage>" to proceed with the quest.
This thread is pretty old but the respawn time should be between ten to thirty in-game days depending on the location and if the game considers the area as cleared or not, but with these type of respawning problems it can seem to get stuck.
For the quest Trouble in Skyrim the command to skip forward to reporting back to Farkas should be -
setstage cr05 20
Or if the body of the target is still there try opening the console clicking on the body and use the command -
On a console the best thing to do is reload a save before getting the quest, they are randomly generated if you go do some other quests for a while when you ask Farkas again you may get a different target and location.
Hey I was giving a companion quest for aela and asked her to follow me as well...during one of the missions of clearing out a cave full of Deathlord Draugres she died by either my force push when she was down or my magic. And she told me to clear some house but now I can't continue the companion quest. Everybody's says "Aren't you running an errand for Aela" and it's been way too long already in real time and in game time. SHOULD I RESTART? Also the quest doesn't show up which house I have to clear out.
