"The Vengeance alley was not registering a ball successfully entering it. This kills many functions of the game, including locks, extra balls, and Vengeance features." Star Trek (Enterprise LE)
"The sarcophagus lock was messing up and returning the ball to the center ramp eject prematurely. The game would wait for a relock, rinse and repeat. Mummy Multiball could not be achieved." Iron Maiden: Legacy of the Beast (LE)
