So everything working as it should then Gun stopped working (no shooting sound before game start or after start, but switch test said it was working) and the ball recognition in the Idol subway is okay as I checked it with a camera, all optos are showing purple in the lens. The problems are the balls once they drop down into the subway to the Idol simply stop there. The gun does not work at all, again even tho the switch test tested good. I have no clue why these two stopped at once. And as always thanks for your help in advance, an amazing group of folks!
