[CL] San Myshuno's apartment is misplaced

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.70.84.1020
What expansions, game packs, and stuff packs do you have installed? All expansions except Get to Work; Jungle Adventure, Parenthood, Spa Day, Tiny Living, Nifty Knitting, Laundry, Romantic Garden, Moschino, Cool Kitchen
Steps: How can we find the bug ourselves? Add a 1x3 tile platform to an upstairs bedroom in the 702 Zenview Apartment (San Myshuno).
What happens when the bug occurs? Both livable floors in the apartment building shifted 1 full "wall" tile directly after I added the small platform upstairs. Now, the top two floors of the building (including the "out of bounds" exterior walls) aren't aligned with the rest of the building. The white band that shows the apartments' original bounds is still in place. On one side it now comes into the living space (the kitchen in my sims' apartment), and on balcony side it hangs out past the balcony. I've tried everything I can to get it back to normal, but since the outside of the apartment is still out of bounds, I can't actually move the walls back to where they were.
What do you expect to see? I'd just like to be able to place platforms in upstairs parts of apartments without the apartments shifting (and having the white "bounds" band in my sims' living space). In this particular case, I'd really like to find a way to get the apartment back to normal.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? No
