No disasters, but I originally had all my tilt mechanisms all set fairly liberal. However, I've since had to tighten them up considerably. I've had more than one player shaking these 20-40 year old machines so damn hard that connections and mechs are failing. My Doctor Who sits waiting for repair and my Paragon had the entire GI go out after one of these episodes. Perhaps poor maintenance on my part, but until the machines went on vibrate they had been doing just fine. I get players want to keep the ball in play, but that behavior only belongs on a new Stern and pretty much nothing else.
