Please help me troubleshoot. Frequently when a ball is in the shooter lane, the game will "randomly" autoplunge on its own. I've narrowed it down to the "d" or "w" drop targets. Specifically when the "w" lowers (or "d" raises simultaneously) during the skill shot, the ball launches. I'm having a hard time with diagnosis because I cannot fire the drops (up and down) while watching the switch test screen. Any ideas?
