Need help with gltch "Hired Muscle" quest. Farkas gave me a job. I must intimidate Stenvar in Windhelm, but He is dead. I killed him earlyer in a quest for a Deadric artifacte. The game doesn't acknowledge that Stenvar is dead and Farkas doesn't give me an other work. So I'm stuck and cannot continu the Compagnon quest line. Anyone can help?

im in the same situation. i tried to pickpocket him very early in the game, got caught and had to kill him.

Yeah, I've already heard of others having the same problem, it's quite a buggy quest (like they all are). I was lucky enough to be able to beat up Belethor in Whiterun. Anyway, there's only one way to solve this, according to the UESP: "If you happen to kill one of the targets before you get the quest, you can no longer finish the quest or get farther along in the Guild. The only way to fix this is to type Setstage cr04 100 into the console". If you're playing on XBOX or 360, you're pretty much screwed. :/ You could try a reload from before the start of the quest, and hope he'll ask you to beat up someone else since it's a radiant quest.
