-Fixed an issue where some cards, artifacts, and classes wouldn't unlock if you had unlocked the achievement for them in a prior patch.
-Added a "Reset Save File" button to the title screen. (This resets all masteries completed, achievements gained, tutorials... EVERYTHING.) After clicking the button, it will notify you that you have to type the word "DELETE". This is so you can't just reset everything accidentally.
-Made saving and loading slightly faster in some cases, by no longer saving and loading worldgen data. (As of patch 0.64, the world is now generated from a single randomization seed variable instead of saving/loading the coordinates of everything.)
