So I didn't get the quest until a while ago, but I had somehow already bought Hjerim and was living in it. I have had the Strange Amulet since I bought the place, a year ago or a bit less. I bought the decoration "Clean up that murderer's mess" and with the journals and stuff about the butcher I knew I had missed something. Anyway I never had the dialogue option with Calixto about the Amulet, and it's still the Strange Amulet, it hasn't changed like it's supposed to and I in can't drop it, it's still a quest item though I finished the quest. Also I was super confused when this guy was in my key-locked house and I had to kill him. Is this the most screwed-up bug ever?
