If your game was connected to a Facebook account, Google Play (Android devices) or Game Center/Apple ID (Apple devices), then you can try to restore the missing progress yourself:
- Uninstall and reinstall the game.
- Connect the game to the social network account to which it was linked.
- A window will appear asking if you want to download an existing game associated with your account. Select the desired farm, dial 12345 and press the confirm button.
