Did repairing your game fix this issue for you? I am having this same issue, no wall bade
under my stairs no matter what I do. I tried repairing my game but still, the base will not show up.
You can usually get the base to show again if you apply wall paint to the stairs. Just select a wall paint and click on the stairs like you would if the base was there. That should restore the base.
Hope this helps.
I have tried this, and that does not fix the problem.
@evanmwogrinHave you checked this Icon shown in my picture, the green marked Icon?
(I don't know how this Icon is called in english)
With this i can make the walls visible.
My walls are already up in game (see photo I attached) you can see the walls are already up.
