Quoted from NightTrain:It would be cool if they would add that option in the next code update. I usually only have time at night to play 1 or 2 games. I hate having to shut it down with 2 in the lock. It would be nice to fire up the game the next night and have 2 locks ready to roll.
I completely agree and always wanted them to stay. Its cool for someone to walk by the machine, see two balls up there and want to give it a go to add the 3rd...
