I'm on dragonborn expansion pack and trying to complete the mission "The path of knowledge". I'm trying to approach Tel Mithryn to speak with Neloth but Talvas Fathryon keeps attacking me. If I sneak up then the woman will speak to me on her own and then he attacks me and she joins in later, if I simply walk up they both attack me. If I sneak past both then Neloth attacks me! What the hell is going on? And you can't kill Talvas either as he comes back to life!!!
