i used magic against Vilkas when trying to enter 'the companions'. Now he won't acknowledge my melee attacks. I can't go into any shop menus, complete quests or talk properly. I used up all my autosaves trying to fix it. Now I have to start all over again, I was level 27 and very far through the main quest!
I've tried getting a bounty and paying it off, but conversations never trigger anything. I tried sleeping, going to jail (no trigger), hitting Vilkas with both shield and sword then sheathing etc. and he is indestructible so I can't kill him.
I might just put the game down until Bethesda patch this, which may mean I will never pick it back up. Shame.
If anyone can think of any other way to fix this I would be indebted. I refuse to start again.
Maybe if there is an alternate way to complete the quest? I heard there are a few ways of getting in to the companions.
