We discovered a bug that caused defeated npcs to be marked as not defeated if the game was exited by going to the title screen and clicking on the Exit button. This bug has been corrected and NPCs progression is no longer reset.
Your tokens, coins, booster packs, tinkers, and unlocked regions are all still saved, only the NPCs were being marked as not defeated. If you are affected by this bug, please DMs us in discord and we will do our best to help you.
Thank you and we sincerely apologize for this inconvenience.
