When you turn off the laptop while running Minecraft Dungeon, then everything created in the game resets. The first time I did it accidentally wanting to turn off the laptop (I turned it off using the button on the keyboard not by settings). This morning I turned the game on and the character creation menu came up, tried to reset the game few times and i still was in the character creation menu, after that i decided to create new character and turned off the game same again and the error came up again. tried 3 times so i can know if the error is random and every time it reseted my characters.
