Lately, in my Games of Thrones LE, the flippers freeze when I hit them both at the same time. They only freeze for a second or so and then, they are fully functional until (if) I strike both flippers at the same time again. I have checked for grounded wiring, all the diagnostics, and for any loose connection, but everything is A-OK. The game works perfectly otherwise. Has anyone encountered a similar problem? Any advice would be appreciated
