I just Ruled the Universe for the first time ever (it is set to 5 balls, though - it was my 4th ball that cleaned up on). Everything went dark, balls drained, I got the ticker-tape parade,etc., then the game gave me another ball to continue playing. After a minute the ball landed in the SOL hole...and never came out. I expected the game to go through the usual ball-find sequence, but all that happens is the ball capture diverter opened and closed every 30 seconds, and now (about 10 minutes later) even that's not moving. The watchdog that checks that a ball is in play seems to have turned itself off.
So now I have to TILT my best game ever...
