I suppose if nothing else comes of this, it isn't a huge issue, but my gamertag has stopped showing up in leaderbaords. What I mean by that, is not that my stats were wiped, they still show up and in the correct position on the leaderboard, just my gamertag has disappeared and only my prestige/rank remain.
I recently played someone who got angry at me claiming I was camping, and they had a lot of kils, so I'm concerned it could because of them, or it could just be random. I'm concerned it's just the start of me losing everything, and I've been working to complete every challenge.
I really have no idea how hacks/mods work in CoD games, even though I know they're relatively common, so if anyone has information on something like this, it'd be much appreciated.
