I'm a very logical thinker, and one thing I love about pins is that if there's a problem, there's always a logical reason for it. Recently my Sorcerer would award the bonus and go to the next ball while I was still playing the previous ball; usually when I locked the first ball or hit one of the lane change switches. So without thinking it through, I pop the playfield, check for shorts, check the switch matrix chart, etc. No luck, and nothing about this problem seems to make sense. I take a breather to think things through logically, and decide it has to be something in the ball trough. Sure enough, the rightmost switch in the trough is riding right up against the ball kicker arm, which sometimes drags the switch wireform along with it. Some creative bending and problem solved. It's all logical.
