Happy to have just joined the club and have a MET that's acting a little strange. The "O" drop target is not registering consistently. When I am in switch test mode, everything seems fine. All switches work as expected. But when playing a game, the "O" only registers about 50% of the time. In fact, if it's the last drop standing, it never registers and the bank won't reset. Oddly, it seems to work less the later in the sequence that drop is hit. So far, I have not noticed this behavior on any of the other switches.
