@metaphasic I a fairly certain that like that, weather will not be an issue, however I can't test it for you, basegame and all :)
@eufl I could have told you that about the roof clipping, it is an entirely different problem sadly. Ea programmed something that shows the roof if your room is not composed of full walls (it is not an exploded room, just not a completely closed off one. However, as soon as you add any half walls, platforms or fences, you get that problem of clipping. The rooms are still proper rooms though. It happens when you connect a non-full-wall to the outer wall of the building. So yes staircase gaps do that, but just connect a regular fence to the outer wall, same thing. Add a platform, same thing... It's a bug or bad programming, but this has been reported already afaik. :)
