Game is borked

cypriano3​  This message is coming from OneDrive, as it's syncing your Sims 4 data and deleting files that apepar to be duplicates or otherwise unnecessary.  The zoneObjects files in particular only exist in a folder called scratch inside the saves folder, and scratch only exists when you have a save loaded, unless the game crashes and is unable to delete the folder.  So these files are extraneous, although that says nothing about the other files not listed in the error.

At any rate, I would suggest getting rid of OneDrive, or at least preventing it from syncing your Sims 4 data.  How to do so is covered in the first post of this thread:

[CURRENT ISSUE] Sims 4 saves/user content disappearing (PC) | EA Forums - 11838402

Let me know if you have questions about the process.

I can't tell you for sure that this will fix the problems you're seeing in the game, but I can tell you that it's possible that OneDrive is part or all of the cause.  I can also tell you that OneDrive can cause other issues, now or later, so keeping it away from your Sims 4 files is a helpful step in general.

As a side note, platforms are not necessarily going to raise any objects on top of them.  If you'd like to raise an entire room, or the whole house, try using the foundation tool instead.
