Playing Skyrim I bump into a random npc called Vilkas, never seen him or doen any quests with him but now all he does is follow me around and open the chat menu whenever he is near me, it's very annoying as I can't do anything when he is near me because he always wants to speak. I cant even fast travel because it counts as being persued and I can't kill him because he just gets back up. Anyone else have this problem or know a solution?
