I have a D&D on location, and it's crapping out so many times I have people putting stuff like this on the game, despite me constantly fixing it. There appears to be an issue where during multi-ball if more than one ball gets stuck in the center VUK it renders the game un-playable - anybody else running into this? Beyond that issue, I've had random reboots, strange behavior from the game. I thought it might be bad software updates but it's still happening after multiple updates... I'm at a loss as to what's happening. Do I have a bad system board or what? See less
