We had an issue on WWF at the NKY Pinball Open where the ball autolaunched while the player who was up was playing with the flippers before starting.
After testing we found out that after 7-8 seconds of being in the shooter lane, if you pressed the left flipper button, the ball would launch. So weird. Only the left flipper, and it was only after 7-8 seconds.
@Shep thought it might be a bug in the ifpa tournament mode. I reset the game back to factory, and it still does it.
