A friend has asked me for help w/his GOTG Pro. It suddenly developed this issue where either one or two balls will eject out of Groot's mouth properly, three of them will limp out really, really slow (the ball furthest back often needs a 2nd kick), and when all four balls are locked in there for multiball #2/later the game simply cannot get even one of them out. Every other GOTG I've played will fire out all four balls hard, straight and fast toward the flippers.
Has anyone else experienced this? What are the first/obvious things to check when I can get back over there to look at it with him?
