When I go to save my game, no files are displayed, and I can only create a new save. So, when I go to load my game, there are numerous save files. How can I overwrite a save so I don't have to repeatedly go into the load menu and sort through all these save files?

Not sure how your getting that problem, when I go to save I get the option to overwrite any of my auto saves and the 1 regular save I always overwrite. And theres also quicksave which only uses 1 slot too. Also the game automatically makes 3 auto saves, it never goes more then that, you should only have 5 saves in total if you just keep overwriting your normal save.

That's odd. Yeah, when I go to save, I only have the "New Saved Data" option.

It's working now.
