I just tested this in a vanilla test save. I had no problem with it as shown in the pic.
I got the stair base for every stair I tested including the one I see highlighted in your first pic. I get the base every time. So idk why you are getting what you are getting with the base. I do have all packs and the game is up to date with the latest patch. The only thing that I can recommend that you try is to do a repair and see if that helps.
Hope this helps.
Ohhh I don't know why I didn't try that. Thank you!
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.
