Got the quest/ring in the prison; killed the beast and chose to kill sinding. killed him in the prison as a werewolf (i believe he was supposed to escape but didn't). Went to the hunt cave, all the other hunters dead. Then tried going back to the prison and another copy of werewolf sinding was there standing over the dead version but he's unkillable. Keeps regenerating. Can't get rid of the ring now.

Any suggestions? Any console cmd to remove the ring?
