I'm extremely new as this is one of the two first two pinball machines I picked up a few days ago.
I have been noticing a occasionally issue where completing the 1-9 roller overs once would register as completing it two times. Like if I were to complete 1-9 it would skip over double bonus and go to triple bonus. When this does happen I can see the double bonus light lit up for a second.
Any recommendations on where I should be looking?
Also does anyone know when the knocker is supposed to activate on here? Been searching around and cant find anything on it
