Even when he is told to follow me he doesn't move from his spot. If I fast travel he appears there but then just sits there and doesn't move. I've tried dropping him and picking him up at the lucky 38 still the same thing.

Anyone know how to fix it? I'm playing hardcoe mode so shooting him till he goes unconscious doesn't work.

PC,XBOX or PS3?

PC windows vista lastest version of the game. I tried turning it to normal mode and shooting him till unconcious and that didn't fix it either.

Sorry I have windows 7 not vista

Tell him that you dont need him. Dismiss him. Make him leave the party. Then go and take him back again. That happened to me with Raul.
