My issue is a weird one (to me anyhow, haha). I can play a 1-player game fine with no issues. If I add multiple players, the game has trouble advancing to player 2. Sometimes I have to drain the ball more than once before it advances to player 2. The weird thing to me is that it NEVER hangs up advancing to player 3 or to player 4 or back to player 1. I'm not good at fixing EM's, so I'm trying to seek out some direction as to what piece of hardware I need to look at. Is the problem more than likely linked to the coin count relay or the player count relay, or neither?

We were recently in the head working on a startup issue, perhaps something got hit? I'll check there too!
