To be perfectly honest, considering the amount of time and effort the devs have put into the game, its entirely understandable, not to mention acceptable that there could be a small glitch like this included on the release date. However, I agree with microsofts ban on these sorts of issues, as people who exploit glitches like this DO ruin the game for everyone else playing it. I remember when Call of Duty: World at War came out, and people were deliberately skipping half the MP maps due to the fact they knew that there were places where people could, and would, glitch on them. Not fun. Bring on the banhammer!!!
