★★★★ Guide



To fix mods and custom content try the 50/50 method:

1. Move all the mods and cc out into a temporary folder on the desktop.
2. Move a few files back at a time. Load the game to make sure it loads and everything is good.
3. Delete the localthumbcache.package from the Sims 4 folder.
4. Repeat steps 1 - 3 till there is no more files to check.

** While your testing, don't save the game. If you find any problems, delete the mod or custom content file.

How To Find Problem Mods and CC -

Broken/Updated Mods: Python/Terrain Update + Get Famous, Nov. ’18

Custom content can become outdated with most new game patches. If the game works when the Mods folder is removed, then one or more of the mods and/or custom content has become outdated and will need to be removed or replaced. EA/Maxis aren't responsible for broken mods/cc. It's up to the creators to fix.

Just wanted to say make sure that you did not accidentally add a sims3 mod, that will cause this problem.

Hi @Valen14lp 



Try resetting your user files as described in the factory reset described in this post:


You won't loose anything. Just make sure to not delete any files  and make a backup.


After renaming, repair your game by right clicking on the game in Origin.


Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.


  • Options.ini (or just re-set all your settings manually)
  • Tray Folder
  • Screenshots/Videos/Custom music
  • Rest of the save games (leave out which is the autosave and no longer needed - if you still have it)
  • Custom content like clothing, hair, skins, make up ....
  • Mods (one by one, making sure they all still work)

The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.

Happy Gaming
