If you're the type to meticulously pore over leaderboard data, you may want to boot up Call of Duty: Black Ops 2. Some users are reporting their leaderboard data has been erased – total play time, points, rank and even zombies performance seem to have been affected.
The forum thread in question only shows a few users complaining of having their stats erased, but we've still followed up with Activision for clarification on whether this is a widespread issue or isolated to a few specific players. We'll update you all as soon as our intel package arrives.
