Unfortunately this has happened due to an iCloud merge that has caused your save data to become corrupted. This issue will no longer occur with version 1.2. But if you are experiencing this you will have to delete your iCloud data, even if you update to version 1.2. To do this, do the following:
- Go to the iDevice settings and select iCloud
- Scroll to the bottom and select Storage & Backup
- Select Manage Storage
- Select Carmageddon
- Select Edit
- Select Delete All
If you have more than one device, make sure to delete the data from both. If you are still having problems, delete Carmageddon from all devices first then clear the iCloud data (check on all devices that there is no iCloud data present for Carmageddon) and re-install Carmageddon.
This does unfortunately mean that your save data has been deleted (really sorry!), but you will now be able to load Carmageddon. What’s more with version 1.2 this problem should no longer occur.
