Fix: The Sims 4 Game Data Incomplete error

The Sims 4 may sometimes throw up a strange error message that reads:

GAME DATA INCOMPLETE.

Not all game data could be loaded. The save game references neighborhoods that have been uninstalled or otherwise are no longer available. If you continue playing, you will encounter missing data and may have unexpected results. If you save the game, there will be no way to recover the missing data.

Basically, the Sims 4 alerts you that some game data is missing. If you continue playing, you may encounter all sorts of glitches.

If you save the game, you’ll lose all chances of ever recovering the missing data.

Let’s see what you can do to solve the problem.

How to fix Game Data Incomplete error in The Sims 4

Close the game and don’t save it

Don’t save your progress with the missing neighborhoods or packs. As long as you don’t save your progress, your game saves should be available again after restoring your packs.

Don’t mess with that save. Instead, start a new one, and navigate to Manage Worlds. Check if one of your packs is missing. If all your packs are there, navigate to the main menu and check your installed packs.

In the worst-case scenario, you might need to load a backup save. Always back up your saves. In case something unexpected happens, you can use the backup files to restore your game data.

Try repairing your game in Origin, and check if the error disappears.

1. Launch Origin
