In any free map that has damage tiles, kill every monster or unit except for one. Then, position a few of your units alongside the damage tiles, and remove their equipment, either by discarding it, or trading it to somebody else. If it works, the game's Enemy Ai will move the last unit on top of the damage tile. It will then proceed to attack any units it can, until it dies from the damage received by the damage tile.Once the creature dies, the glitch activates. Even though there's no enemies left on the map, the game doesn't recognize the last monster as "dead", and the match continues until you either Suspend and Restart, or Retreat from the fight.If this occours during the actual story mode, as opposed to a Monster Map, the current chapter will become unbeatable, requiring you to restart the chapter.
