After some Googling and experimenting I've figured out ways to get rid of these floor tiles, but it really still is undesirable stair behavior, especially because the game will fail to properly recognize stairwells like these as rooms, leading to problems with applying wallpaper per room, wall trims, etc.
I know how to get around it now, but like I said, it really is rather problematic and more of a design flaw more than anything.
I could still upload a build to the gallery if you'd like, though. Does it need to be a specific kind of building or can I just upload a mock up lot of cases where configurable stairs cause issues?
Hi, sorry I took so long! There was some IRL stuff I had to deal with.
I've made a little mockup lot with a configurable staircases that show the behavior I mentioned. I roughly marked landings and openings with fences and banisters, so you should be able to tell which floor tiles are unwanted.
I realize there are ways of getting rid of them, but it's convoluted and not very logical. It's especially problematic with basements underneath raised foundations, as you can't reliably get rid of those pesky floor tiles refusing to be removed. When you do, the floor geometry opens a hole into the void.
Again, I know that I can remove these tiles (with the exception of stairs leading to basements that are on raised foundations), but the fact that stairs behave this way is not exactly desirable.
I included a screenshot of the lot uploaded to the gallery. You should be able to find it! 🙂
