Wondering if anyone has had this issue before, happens roughly every 10th first lock. I will shoot a ball into the magneto lock area and it goes in and locks fine, however then the game dosent serve up another ball, does a ball check and then ends the ball like I drained. It will then go back to normal serving up the next ball of 3, I have only ever seen it happen upon locking the first ball. Guessing its a switch or opto problem?
