I've got two gamertags which I store on a memory stick so I can switch back and forth between two consoles. I finished playing Saints Row The Third on my other gamertag and thought I'd start a new game. Before the opening even finished, achievements started unlocking. They are all things that would have occured much later in the game. Now I'm all paranoid it's going to look like I modded my gamerscore (lol). So why did that happen?
