I've had MM8 installed and running on Windows 7 for quite a while, but hadn't played in a long time, and when I went back to play again this new bug has appeared...

In short, I have numerous saves already from playing the game for a while. However, now, whenever I try to save my game, regardless of if it's a new game or an old save loaded, the game isn't saved, but instead a new copy of a particular save (The last one I made before I stopped playing for a long while) is made in the slot I try to save in.

As you can imagine, this really ruins the game :/
