Hard to explain how i found it, but basically it started with me being able to click some buttons while the game was resetting. Then with help from the FPSbypass (from mathisfun and shadowbulb) i was able to open up options, then return the main menu, while the game was resetting a seed. which crashed the game.
not useful in anyway (to my knowledge) and just a funny crash
also probably not humanly doable (unless your aim and speed is that cracked)
