Guys, if you mess up a save, just click My Saves, and you'll see a little seven (7) next to each one. Click it, and you'll have all of the previous saves. They'll all look the same, so click any one, and you'll see it's different. I messed up Arctic City 2, and I didn't know this. Thankfully, I had a stamp with the latest version. :D
