Firstly I didn't know what section I should be posting something like this as it's my first time doing so. With the default profile (kicks) Horde 92-94 I've experienced the same issue with three characters now. When doing the quest "A Centurion Without a Cause" it will continue the same behavior which is to talk to him go out about 50 yards and return to talk to him. This is after the mission is complete and he becomes a follower, none of my characters will move on to the next part of the mission.
