Quoted from Guinnesstime:I've gotten that bug once. No mods.
I spent a fair bit of time investigating as we had plenty of reset issues with our machine when we got it. The game also took a long time to start up. I think some of the resets would be caused by a faulty servo. You can tell if your servo is faulty, it will tremble or not work at all and cause the machine to reset. We have not had any reset issues since we updated to the latest code.
Cracker of a game. Well done John Borg, Zombi, Dwight and the rest of the crew at Stern.
