I fiinished Jahan's questline and, due to an AI roll, he is now doomed to face is worst fears for all of eternity. After leaving him in the Abandoned Shack I went back to the Hall of Heroes with only three people in my party but none of the companions will join. I have switched out my third companion, restarted the game, restarted my computer. Not sure what happened. Anyone experience this issue before? I've been looking online but can't find anything.

I am with same problem.
Anyone can help us?
