Problem: Bug

Built a tower bigger at the top than at the bottom. Put a map room on the roof. 1st time I logged in after, it was gone. The second floor down had an invisible spot that i couldn’t stand on or interact with anything. Also pushed the camera through the walls. Reset the server and now the map room is gone along with the weird spot.
