There is a bug attached to the newest Microsoft xbox 360 updates. If the bug effects you it will wipe out your achievement earned for all games. If this support thread is any indication, the issue hasn’t been resolved for everyone, and some gamerscores remain broken and missing. The problem is effecting a large amount of the gamers that have updated there software on games like Mass Effect 3 and Modern Warfare 3.
What went wrong?
This was a mistake in the software coding that Microsoft made. a very careless mistake that effects most all gamers and resets all there achievements. This is by far one of the biggest software mistakes Microsoft has ever made with xbox 360. They made a bug where when you add a new patch for any game it will try to bring your old game data from any other xbox to your new xbox. The problem is if you did not have old data it will bring in blank data for many things including achievements.
How to Fix it
