I played MC Dungeons for 3 hours offline in the car and the game crashed. When I relaunched, the enchantment points that I had been saving for thorns had all gone away. They did not reset to zero, but they went to the exact opposite of the amount that I had. I had NEGATIVE 13 enchantment points. This was not just a visual bug, I could not use any of the points at all. When I earned more through leveling, the points got closer and closer to zero. I highly doubt that losing my earned enchant points is intentional game design. I still have not recovered from this bug and have stopped playing as a result.
