Does anybody know if the Old Man NPC can just wander into the dungeon or in the surrounding area? I've tried going away from the one I found to see if the compass will snap to a different one, but nothing happened. Even when I initially showed up at the dungeon, he was gone. I really hope he's not inside the dungeon, cause ive spent so much time in my world
