I am in the beginning of Act 2 and while I was in the prison, I decided to explore the battlefields. I must have been really close to the stairs (exit) of the prison, because now when I leave the battlefields and come back to the prison, I am stuck "behind the walls" - in the black area - where no one is supposed to be and since I can't walk through the walls, I am stuck. I can reload from a saved game, but I will lose a lot of game time and if there is a way to fix this, I would prefer that. I have seen monsters "behind the walls" in several maps.
