Even if you've done this on other games (like I have) you'll have to do it again (it was reset to 100 for some reason). I have not gotten far in the game, but so far it has been saving just fine. Hopefully this will solve everyone's issue.
Great game, by the way. I loved the first one, glad to see a sequel with the same great taste, new and improved. Would love to play another game that was a different concept but with Burrito Bison in it.
