The chests spawning on the third level of the port can be overwritten by walls in divided rooms if they cross the middle of the room where the chest spawns. The chest will still spawn if the room is divided but the wall does not cross the center of the room.
Additionally(and probably not a bug) chests do not spawn in rooms without doors.
