Hi! I'm glad you are following your journey through CH! This is one of the best feedbacks I get, when players actually play the game.
Sorry for this error. Did you try to start a new game and then use the save/load system in the menu? Maybe your save file got corrupted.
It's a problem on our end, and we are going to work on a more robust save and load system.
Please try to use the Menu and thank you again for the feedback and you can expect improvements coming soon.
