When starting the game I get the following error message
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, 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.
This message usually occurs if the data from an expansion or game pack is no longer present in the game, mostly when you uninstall the packs and try to play a save game that was saved with those expansions.
It seems some data gets lost without you uninstalling something, though
- Close the game and do not save it.
- Repair the game through Origin.
- Resetting the game to factory settings without reinstalling
- Make sure you still own all the packs. If not, contact support
