The 1.2 version of the game contains many bug fixes and new assets that affect the content of the game. Unfortunately, this may interfere with some of the save points you have set from the previous version of the game. Please try to load all of your saves from 1.1 so you can confirm which specific saves are causing the game to crash. You will need to remove these saves from your %appdata% folder on your computer. As much as we have looked in to this issue, these saves cannot be recovered. We apologize for the inconvenience!
