so today i played for a few hours, trying to get my FAL maxed out so that i could move on to the next weapon. i was successful in maxing out and earning gold camo. i then moved on to the next weapon, and completed most of the challenges for the camo unlocks. during all of this, i completed my 9th prestige, moved into the 10th prestige and made it up to about level 5 or 6 before i decided to take a break. when i got back online hours later, i got a message saying that my online file was corrupt or something to that effect, and i was reset to 9th prestige, level 48. is this a known issue or something? i am really frustrated.
Well, it could have been worse. There are a few reports here on these forums from gamers suffering the same bug and some got reset to level 1 no prestige.
Send this guy a private message and he can restore your rank. You'll be in for a long wait though. He's weeks or even months behind schedule.
