September Patch Speculation 2019 (Now Out) Emergency Patch Out Now Sep 17th

I am having tons of problem with the new patch.
I was waiting so impatiently for those stairs and they are now my nightmare!

If I place them in the basement, the house suddenly gets pushed up the ground (creating a hill).
If I place them inside the house and I used columns those will show as columns for mid or high level walls, instead of low walls (and I have to take the walls to high and low to adjust it). Anyone like me? If the thread is wrong please let me know (searched for a place to go and write bout it but couldn't find it).
