This silly dwarf got stuck in a corridor going out of the Arena. He refuses to go any further to the left (because of door maybe?), he refuses to switch places, I don't want to fight him and have no way around, so it looks like I'm going to need to wait at the other end for him to come back. I think this is not intended behaviour and I suggest doing something to prevent it. (can't leave Arena area, allows to switch, or can wander wherever so he won't get stuck? Any of these should work.)
