Maybe they have, I got my game middle of last week and the pop up mechs started failing within the first day. If I run the coil test they all just pop up about halfway and drop back down. I have investigated somewhat looking for disconnected wires, but I have not looked for just rubbing. I hopefully can spend some time later today looking for if they rub the playfield. There is a lot going on under there. Otherwise things appear to be fine.
