Would anyone know why my 10th prestige isn't sticking. I have been in multiple lobbies now and killed a zombie to get 10th and then game ends and I go to multiplayer to get a kill once done and I got to zombies or turn off and restart the rank is back down to where it was. I do get a message saying something about leader board data wrong and reverting to last rank save or something like that. If anyone can give me advice so I can fix this issue that would be appreciated, thanks.
