[FIXED] [CL] Elements disappear from view in open story apartments

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? 1.47.51.1020
What expansions, game packs, and stuff packs do you have installed? Digital Deluxe, City Living, Get To Work, Get Together, Spa Day, Laundry Day, Perfect Patio, Holiday Celebration, Grim's Guitar
Steps: How can we find the bug ourselves? The lot I know of is "1 Torendi Tower Penthouse", granted I have only checked 2 lots for this, the other one being the 64x64 lot in the Get Together world which did NOT have this problem. For all I know a whole lot of lots have this same issue, but I don't know. So, pick the Torendi Tower Penthouse in any save of the game and place a room down on any level higher than the "ground floor" then delete the floor with the bulldozer tool, opening up the ceiling for the room below and enabling you to see into the room that is below the room you just placed.
What happens when the bug occurs? Furniture/sims/stairs/doors are invisible when viewed from the higher floor of the double height space.
What do you expect to see? I expect to see the furniture/sims/stairs/doors below, like I used to be able to before an update broke it.
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? Yes
Please describe the patch or change you made. The game update that came just before Get Famous was released is what broke this for me. It worked fine before this.

‌

- Furniture that is below the open ceiling/deleted floor will be invisible when viewed from the upper level. Sometimes, /some/ of the furniture is visible (but not in my personal save, just a random one I opened to check the issue), but some is still invisible.

- This includes any stairs that you have placed where the floor above them has been deleted (for example, if you have an indoor balcony and stairs that lead down into a double height room, you can not see the stairs anymore if you are viewing the upper portion/balcony of the double height space).

- Sims will be invisible.

- Doors will be invisible.

- Sims and furniture DO cast shadows, AND can still be clicked on. They are also visible fine when viewed from the floor level that they are actually placed on, just when you move the camera up (eg. if you have an indoor balcony or a double height ceiling) they are suddenly gone.

Attached images show a hole I put in the floor of the lot that is already built when you open a new game. In the one where it is viewed from the higher level, you cannot see the counters/pot rack/etc, but in the image where it is viewed from the floor the counters are placed on, they are clearly still there.

Ways I have attempted to fix this:

- Turning laptop mode on and off.

- Raising various graphical settings.

- Removing all of my mods.

And as I have said, some lots actually still work fine for me, so I know it is not a graphical thing.

I should also add that no matter what level your camera is set at, everything still looks fine when viewed through windows. With this visual glitch, it's almost as if the floor is still technically in the way somehow, even though it has been deleted, as you can see nothing through it.

EDIT: Augh I just found that someone else already posted this, I read all the items in the compiled lists first but I guess I should have stalked the forums myself as well.
