How to test your save on fresh folder to make it vanilla
It is really important to that you remove all mods/cc to see if you have the issue without mods as well. To do so, renaming the user folder is the easiest approach. You won't loose any progress this way cause everything is still there in your old folder.
- Close the game
- Find your user folder in Documents\Electronic Arts\The Sims 4
- Rename that folder to Documents\Electronic Arts\The Sims 4_OLD
- Start the game. A new user folder will be created and everything is back to the way it was when you first played. All your options will be reset and your saves will be gone.
- Start a new save and test if the bug occurs
- Go to Documents\Electronic Arts\The Sims 4_OLD\Saves and copy all your save games over to the new folder Documents\Electronic Arts\The Sims 4. Make sure to copy and not move.
- Test the save you have issues with.
How to revert your old state you had before testing vanilla
- Close the game
- Delete the folder Documents\Electronic Arts\The Sims 4 (this will make you loose everything you tested on the vanilla state)
- Rename Documents\Electronic Arts\The Sims 4_OLD to Documents\Electronic Arts\The Sims 4
- Start the game. You should now have everything back.
