Quoted from chill:I just saw that Buffalo Pinball is currently hosting someone streaming GOTG on Twitch.
It looks like the game is having ball management problems, ball search not uncovering all the balls. I am having a similar issue on mine that crops up with the ball getting stuck behind the orb target, game goes into ball search trying to find the ball and have to reboot. Looks like some kind of bug as it doesn't happen all the time.
