I've got my game set up to NOT dump any leftover balls in the Castle Lock between games. When I turn the game off and back on again the balls locked in the Castle Lock will dump into the plunger lane and get shot out onto the playfield in order to drain before a new game can be started. The annoying/noisy thing is that the Mist Ball also drops out of its slot, the Mist motor runs from one side of the game to the other, All the solenoids start firing, and finally the Mist Ball is reloaded into its spot. Is this normal? Seems like a lot of unnecessary hullaballoo going on just to empty the Castle Lock.
If I set the adjustments to purge the Castle Lock between games, it still goes through the whole dog and pony show of balls dumping and solenoids firing btw. For some reason I feel like the Mist Ball should be staying put and the solenoids don't need to be firing. It seems to be acting exactly like a Ball Search to me.
