I couldn't reproduce, but when I played it today, I couldn't activate the Joker major villain mode. I hit the targets above the "J O K E R" letters as usual to get the phone to ring, but the hits didn't register. When that game ended, I played another and was able to light up the Joker's letters and the Joker icon to light up on the 4 major villains icons - those 4 round lights a few inches above the flippers), but as the phone started to ring, the ball drained down the left side. However, the ball was saved and the phone was still ringing. I hit it, and it started the Penguin's major villain mode.
