I had 580M on ball one with two extra balls. All of a sudden the scoop stopped recognizing balls while I was in ninja multiball. I got two balls rested on it then the third drained. It did a ball clear, then I shot one back in only to have it not recognize that. The other ball drained and out of nowhere it resets to a new game.
I am sure it is something stupid I can fix, but WTF! I had a sweet game going!
Sorry, I needed to rant to people that would understand my frustration.
