Never had this happen before. Carth wont move or allow my pc to talk to him. He will only move if i have him selected as lead. Also can only talk to him if is lead and have him start conversation with my pc. Everything was going fine until he started talking about saul, now he is like a dead weight and its getting annoying having to drag him along. Any ideas (other then starting new game, id rather put it away for a year again)
Have you tried saving the game, exiting and reloading from the save? I've had the same thing happen from time to time with different characters, and sometimes that's all it takes to get the game going again.
