technically, it crashign in the "middle" of a session fo AoT ends the session at the point of it crashign thus making the middle the end, however it must crash before that so as to be in the middle, but the middle being moved, the point of crashign moves thus the end moves
this repeats infinently as when going by halfs twards a specific direction (in this case, being the point in which you commence the game) and creating a paradox
that is probably what is making your game crash...
computers dont handle things like this very well
