Re: Update deleted my sims 2020

@JamieBlackBeak  It's strange that your old saves wouldn't be recognized, since they're in the correct place.  See if loading them in a clean folder helps.  Move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, then launch the game to create a new folder.  Copy over one save from the old folder to the new one and test.  If it doesn't show up, copy over a different save and test.

You can also try loading the backup versions of the saves, although you'll need to delete the .verx (x being a number from 0 to 4) on the end of the backups.  Since you're copying and pasting, you can mess with the new copies however you want, and the originals will be intact in your old folder.

If none of your old saves load, is it possible that one or more packs you own is no longer installed?
