whenever i go online and play then go to main menu, i get a message saying something like "Your persistant rank as 10th prestige: rank 65 commander has been corrupted and we restored your rank to the recent backup of 10th prestige: rank 65 commander." So i cant save any challanges i complete or anything like that. If anybody can tell me how to fix this then it wil be greatly appreciated and i will plus rep you also
