This is a pet peeve of mine that I would love to fix, but I really don't know where to even begin looking for a way to do it. Would/should it be possible to make the floor tiles that are automagically generated by doors deletable? (Actually I'd be surprised if it *can't* be done, as I discovered that they delete just fine in TS3... :p) Can anybody point me toward the place where this is controlled in the game?
