Foundation/Roof bug

I’ve been forgeting to report this but basically if a foundation is deleted with a roof above it you cannot place a foundation back down the roof must be deleted. (I have tested this) if you don’t delete it
the floor the foundation will just stays red wether if you got cupboard access or not (obviously)

So… If foundation was placed and had a floor above it and foundation got removed you cannot place another one back unless you destroy the roof.
