I believe I encountered a bug this morning that's not been mentioned in this thread yet, on a pro.

Got loop jackpot going, and then hit the right orbit to lock ball three fr trooper multiball. It loaded two more balls for trooper multiball, and then sat there on the trooper status screen with the three balls trapped by the post until the ball search kicked in and dropped the post.

There's a bug with the scoreboard display on my Pro. Can someone verify it on the LE/Pre?

You can use the left and right flipper buttons to move forward and backwards in the high scores list. When using the right flipper to advance, the score board skips over a screen. So going forward with the right flipper we see the following:

Screen 1: Flight of Icarus Champion/FOI Combo King/Hallowed Be Thy Name Champion
Screen 2: Aces High Champion/Aces High Air Ace/Two Mins To Midnight Champion

When on Screen 2, if you use the left flipper to go back a screen, rather than getting Screen 1, you get:

Screen 3: Hallowed Be Thy Name Escape Artist/Rime of the Ancient Mariner Champion/Fear of the Dark Champion

Going back from Screen 3 brings you to Screen 1.

If you watch very closely, it looks like what's happening is that when on Screen 1 and you hit the right flipper, the screen immediately changes to Screen 3 (i.e. the missing screen) and then scrolls to Screen 2.
