After going through the "Room_Builder" file quite thoroughly I'm a bit confused. There seems to be some parts missing in some of the room borders/ceilings. How would I go about recreating what's in the 2nd example image (on the right) with one of the 3 wood borders? That protruding wall at the top (between the plant and the radiator) seem to need a ceiling piece that does not exist in the wood ones. Am I missing/misunderstanding something or is that just how it is? Thanks in advance.
