I understand that the binary search is meant to narrow down problematic mods.
By culling every half of the group till you narrow things down.
But here, if the game launches successfully, the search stops if I press [Game worked] while minecraft is running.
I think it would be best to have a warning that you should only press [Game worked] after closing the game window; otherwise, the binary search automatically stops.
Maybe add a pop-up warning telling you to close the game window before proceeding.
Or have it so that when you press [Game worked], it automatically terminates the running minecraft session.
