First off, let me start by saying welcome to EA’s “Answer HQ”.
Answer HQ isn't just an ordinary message board or support center. It's a new approach to our community experience and a fun way of helping other players or to get answers (from players & experts)and get back in the game!
If you come across the error that your cloud save cannot be synced, you can try to manually overwrite it with your local one.
- Deactivate cloud sync in Origin
- Launch the game and play to create a newer local version of the saved data
- Close game
- Activate cloud sync in Origin
- Relaunch game, you should now be prompted if you wanna overwrite your cloud save
You can now overwrite the potentially corrupted cloud save by choosing the corresponding option.
