Forum:Leaderboard Glitch

Unfortunately, I have fell victim to the faulty leaderboards on Black Ops Zombies in a similiar fashion to many other players. My highest online round on Kino Der Toten on the Xbox 360 was Round 27 and one day without any reason my record was changed to the final round of a random match that I had played (and quite a bad one at that.) Now my record is stuck at Round 10, yet oddly enough, the kills and points from my Round 27 match are still on the leaderboards. Does anyone have any helpful information on this subject or is everyone just as dumbfounded as I am?
