I need to delete a game app data from iCloud but not my iPad I have a game where a glitch in the system has caused the Game Centre data in iCloud to be out of sync with the game on my iPad.

I want to delete the iCloud data and then reconnect the game so it then loads the data from the existing progress in the iPad back to iCloud / Game Centre - any ideas.

Please do not post on tips how to delete the app from the iPad.
If the data is backed up on iCloud. You can manage the storage on your Mac.

System Preferences -> iCloud -> Manage Storage -> Select the Backed Up Game -> "Delete Documents and Data"
