Quoted from Chalkey:
A customer just told me they started "top of the charts" by holding in the flipper buttons. After completing their game they played a normal game and it had a perpetual ball save. He said ball save was not lit, but ball 1 never ended. He restarted the game after 10 minutes. Anybody seen this?
I believe I read someone post this a long time ago. My guess is old code.
