how do i get back all my data????

@LoveisLove767  Okay, let's try this a different way.

• Go into Documents\Electronic Arts, click on the words "The Sims 4," and change the name to "Backup"
• Launch the game, get to the Main Menu, enable mods and custom content, and quit
• Go into the Backup folder, open Mods, right-click on ONE of the folders inside Mods (one that doesn't have the word "copy" in the name), and select the option to Copy
• Go into Documents\Electronic Arts\The Sims 4\Mods, right-click in the empty space, and select Paste
• Back up one folder, to The Sims 4, and delete localthumbcache.package
• Launch the game, start a new save (no need to spend much time on it; this is just for testing), and make sure the mods or cc items you just copied over work in-game
• Repeat the three steps above for another subfolder inside Backup\Mods, and another, and another, until you've tested all of your mods and custom content

If at any point, the game starts crashing, hanging, freezing, whatever, stop and let me know.
