1. I am told I already have someone helping me when I don't. So, nobody will follow me. I completed Dawnguard.
2. Purity Quest: Valkas will not follow me to the tomb. He always walks off once I fasttrack there. I tried walking with him from Whiterun. He follows me a short way, then walks off.
3. Werewolf Cure: I cured myself at the tomb, then became a werewolf again via Alesa at the Companions. I completed the werewold perks. Now the blue file pedistle will not activate for me to cure myself gain. I saw a post that you need to cure Valkas and Farkas first, but Farkas does not ask to be healed and Valkas asks, but will not follow me to the tomb. I am disgusted since i replayed the whole game for the Dawnguard effects. Now I cannot get healed or heal the others. I have 3 witch heads in my inventory.
