Quoted from PinMonk:I don't think winter is coming was stacked with Blackwater, and it was both, not just one flipper. Really freaked me out because I've never had that happen before and there were a lot of balls in play. It's a friend of mine's, on location, so I don't get to play it a lot, but I'm going to help him get 1.26 on it so if that was a bug maybe that will take care of it.
That will happen if you flip both flippers at once sometimes. The node 8 overload protect kicks in thats why flippers and lower lights will go out for a second.
