Re: [FIXED] Save Code Error: 0
@oreosimmer01 Please create a new save and see whether you can save your progress. If you can, then the issue is probably your existing save, but you can try recovering a backup copy, as described here:
https://sims4.crinrict.com/eng/2014/09/recover-backup-save-game/
If you can't save your progress in the new save, try playing in a clean user folder. Move the entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content. Don't add anything to it yet; just start a new save, again, and see whether you can save your progress.
If the new save in the new folder works, you can copy over your existing save and test it as well. If it still gives you trouble, use the manual method to recover the backups and add them to the new folder as well, then see whether you can save with any of those.
If you do see an error message at any point, please post a screenshot.
