Many (including myself) have had games ruined due to lost balls. This seems to be common across several tables, on several platforms. Why doesn't calling an attendant fix this? If the table does a search, and the player is not holding a flipper in, it should assume the ball is lost and allow you to reset it. This happens more often than stuck balls, and is more damaging, since you must abandon your game, and lose your score, along with whatever goals you may have completed. I am having a hard time imagining how some people could take advantage of this to cheat, and don't see why it hasn't been implemented.
