Re: [FIXED] Problems playing Sims 4 on the 16" MacBook Pro

@SSeraphism If you are getting that error you may need to try a few things. Please bear with me as I don't ever use Mods or CC on my lot, so there may be additional steps that others may add that I'm not aware of. I would try this, though:

• You said you removed your CC. It's possible there are remnants cached in that are affecting the game still, so you could also try removing the cache file, if you didn't do that when you removed the CC:
  
  Spoiler

  How to delete cache:
  • Exit your game and Origin
  • Go to Documents > Electronic Arts > The Sims 4
  • Delete the localthumbcache.package file in your “The Sims 4” folder (your game will re-create this folder next time you open the game)
• After doing this, given the error message you're getting, please try replacing the floor tiles with a non-CC flooring.
• If replacing the flooring doesn't fix the issue, please try re-tracing each room. To do this use the wall tool and trace each wall in the room all the way back to your beginning point to make sure the room completes. This will normally re-create the floor and ceiling upon completing the room trace. You may want to activate the MOO cheat first to reduce or avoid deleting things while doing this.
• If the floor is still missing please try to rebuild the floor.

Please let me know what worked, if one of these things helps, or if you need further help & troubleshooting. Thanks!
