As endlessly fun as the Sims 4 is, it isn’t a perfect game. Much like any other game, it has its flaws and bugs that can trigger players or downright annoy them. One instance of this is the Save Error Code 0 where players cannot save their game’s progress. Sadly, this is a fairly common problem with the game and is usually caused by a corrupt auto save. Unfortunately, once you have this bug, you practically have to start your game all over. Nevertheless, it is fixable and preventable.
Here is how you resolve the Not Saving Code Error 0 in the Sims 4.
How to Fix Not Saving Error Code 0
Error Code 0 is one of the most common saving errors in the game. It basically resets your progress with the game as it disables you from saving altogether and the fix involves creating a new save file itself.

If you encounter it, try removing all the mods and the cheats you have installed. Check if that solves the problem. If not, try this:
- Go to your game’s file directory, and then look for the cache folder.
- Delete all the cache files.
- Move your saves folder to your desktop
- Start the game to create a new saves folder
Your game should now be back in order. However, doing this step also removes your existing games. So beware. As dreadful as this error is, there are some things that you can do to ultimately prevent it.
How to Prevent the Not Saving Error Code 0
This issue is most often caused by a corrupt auto-save, particularly the slot_ 00000001.save. With that being said, we highly recommend that you do not rely solely on auto-saves.
Take note also that when the game crashes unexpectedly, it would likely corrupt its save.

After starting a new game, make sure that you save it under a new name so it’s saved to another slot entirely. Save regularly and try to use the ‘save as’ option more to have multiple saves you can always go back to whenever some problems pop up.
