i’m not sure if this counts as a bug or not. it could be that this is just how the exterior roomtype works. but i figured it’s worth sharing incase it is unintended.
Exterior room type is a little special. In particular room zero is a special Exterior room that encompasses the outside surroundings. The Mansion levels have additional Exterior rooms between their wings. I’m in the middle of removing the special exterior room concept. I’ll have to look at what you’re doing in more detail later.
