Hi. I noticed a bug where if you have a save game in slot 2, the next time you load up the game, it would override whatever was in slot 1. The same would happen in slot 3. The newest save seems to automatically override all the older saves.
Yes. As far as I remember, that's how it will work. It only doesn't overwrite games you've manually saved. But I'll check to see if there really is a bug there.
