Hey Jottomadai
I'll look into that. Was this on the Itch or Steam version? I'll assume on Windows?
Regarding the lost save data: There should be a "fallback" folder in your game directory, with backups of your profile save file. You should be able to restore your progress by copying one of the recent fallback files into your "saves" directory and renaming it to prof_save_crypt.txt.
I hope that works for now, I'll look into the launch crashes.
