So a month ago my Hobbit said that it was missing a ball, ejected the balls in the trough and only 4. Looked for the missing ball on the play field and no stuck ball. Put in another ball and all is good. Last night my 11 year old says that it is giving 2 balls on the plunge. Eject the balls and now there are 6 balls in the trough. The missing ball shows up a month later. Haunted?!?
