Quoted from bobnatlanta:Sorry - that might help. They are the Chase Loop switches. Chase might advance, and then again, it might not. Same with hurry up. I've tried it with a ball and with a screwdriver pushing the switch all the way down. Same performance. Switch edge works, game only inconsistently.
Try adjusting the wire actuators.
Switches in a fast loop orbit like that can be picky about exactly how the wires are bent.
Seen it before.
