Started messing around with this because I'm fond of basements. Everything worked nicely at first and I was able to delete floors without the irremovable blank slate appearing, but as time went on and as I added more rooms the bug returned. The irremovable blank floors here can't be interacted with through any means whenever I try anything.

Edit: Kept messing around with this and I can't really discern what causes the bug to come back. I built the same basement but built rooms in a different order and the bug kept popping up at different moments, it's very strange. It seems to come up far more often if you're editing a first basement story after you've built one below though. It doesn't like me altering walls in any way.
Edit 2: Getting a lot of weird stuff. If you look at the first part of this image, I have a room on the first story of the basement and everything is as I wanted it. Let's say I want to replce the style of wall - if I change that wall the game will put in a floor that covers the rest of the basement. Deleting that floor that the game forces will yield the irremovable floor bug.
