[OPEN] Round rooms have blue ceilings/ceilings don't get painted properly

I've found an issue with the new rounded walls in the game that came with the new patch update. When playing with the walls I noticed that even when there is a ceiling covering the enter room from the inside up view of the room there is a hole in the ceiling. Shown in the files attached you will see that there is a ceiling with no holes, however when you look up from inside the room there is a hole I the ceiling.
