Sims 4 Error Code 0 appears when the game cannot complete a save operation, meaning your progress may not be written to disk. This is a high-severity issue because repeated failures can result in lost gameplay, corrupted save files, or an unplayable game state. Common causes include corrupted save data, full or write-protected storage, broken game files, or conflicting mods and custom content.

How to Fix Error Code 0

  1. Back Up Your Existing Save Files Immediately

    Do NOT skip this step. Troubleshooting without a backup can permanently delete your save data if something goes wrong.

  2. Check Available Disk Space

  3. Delete the Sims 4 Cache Files

  4. Remove or Disable All Mods and Custom Content

    Outdated mods — especially script mods — can corrupt save files permanently. Always check that your mods are updated after any Sims 4 game patch.

  5. Repair the Game Through Your Game Launcher

  6. Check and Fix Save File Permissions

  7. Try Saving to a New Save Slot

  8. Update Graphics Drivers and Windows/macOS

  9. Reinstall The Sims 4

    A reinstall will remove all local game data. Only restore your Saves folder initially — do not restore Mods until you confirm saves are working correctly.

When to Call a Professional

If you have completed all steps including a full reinstall and Error Code 0 persists, the issue may be related to a failing hard drive or SSD that cannot reliably write data. In this case, run a disk health check using a tool like CrystalDiskInfo (Windows) or Disk Utility (Mac). If the disk reports errors or failing health, consult a computer repair technician to diagnose or replace the drive before your data is permanently lost. Additionally, if your save files are critically important and appear corrupted beyond recovery, a professional data recovery service may be able to retrieve them.

Frequently Asked Questions

Will Error Code 0 delete my Sims 4 save file?
Error Code 0 itself does not automatically delete your save, but it does mean the last save attempt failed — so any progress since your previous successful save is not stored. Repeated errors or incorrect troubleshooting attempts (like deleting the wrong files) can result in data loss, which is why backing up your Saves folder before troubleshooting is critical.
Why does Sims 4 keep getting Error Code 0 after a patch?
Game patches frequently break mods and custom content, which are a leading cause of save failures. After any Sims 4 update, you should disable all mods and CC and test saving without them. Check the Sims 4 modding community (such as ModTheSims or the r/thesims subreddit) to see which mods have been updated for the new patch before re-enabling them.
Can I recover a corrupted Sims 4 save file?
Sometimes. The Sims 4 automatically creates backup save files with a .ver0, .ver1, or .ver2 extension in your Saves folder. Navigate to Documents\Electronic Arts\The Sims 4\Saves, find your save file, and look for versions with these extensions. Try renaming the most recent backup to remove the version extension and see if the game can load it. Results vary depending on how severely the file is corrupted.
Does Sims 4 Error Code 0 happen on console (PS4, PS5, Xbox)?
Yes, save errors can also occur on PlayStation and Xbox versions of The Sims 4. On consoles, common fixes include ensuring you have enough storage space on your console or external drive, checking that cloud save sync is enabled and functioning, restarting the console, and rebuilding the PS4/PS5 database (through Safe Mode). If console storage is full, delete unused games or move content to free up space.
How do I prevent Sims 4 Error Code 0 from happening again?
To prevent future save failures: regularly back up your Saves folder to an external drive or cloud service; keep mods updated after every game patch; save frequently using Save As with different slot names to create natural checkpoints; maintain at least 5 GB of free disk space; and avoid exiting the game abruptly or letting your computer sleep mid-game, as this can interrupt the save process.
