I just bought a Terminator 2 machine and was playing through the settings a few days ago and when I returned to playing, the extra ball is gone. It actually tells me when I get an extra ball, but I don't get the "knocking" sound (the knocker does work, I tested it) and also I don't actually get an extra ball. Also I don't have an extra ball award either. I don't know what I did. I have it set on medium difficulty, 3 ball, and install add-a-ball installed. Any ideas? Thanks
