I'd like to add to my post by saying that this only happens with this particular stair shape. I'm not sure what it's called, maybe a spiral? Since this is something that can be created in the game, it should be functional too (by having that square at the top). It's not a Z-shape like I said before. The other configurations do work.
To make this staircase, I first rotated it to make three levels of stairs. Then I took the arrow closest towards me and rotated it left, like this.
That's where the problem is. Posting this for future clarification.
the height of the landing can be adjusted. If you do this will that fix the issue?
When I try to adjust the height, the shape of the stairs change completely. They straighten out and won't stay in the shape I have them in. I tried to adjust it a bunch, even changing the wall heights, and the only solution is to change the shape. So that's unfortunate.
That doesn't seem to happen for me. The hole goes away if the stairs are deleted. Are you able to cover it with a flat room? (Replying to Jamell)
