Just got my first NIB ST Premium and am having some trouble with the vengeance drop target. When the target is up after you lock a ball, it will not drop down afterwards to return the ball causing the ball to get stuck. Ball search doesn't drop the target either and if I do a coil test on the down target when there is a ball behind it, it doesn't do anything. However, if I do a coil test down with no ball stuck it works just fine (and this didn't happen with vengeance multi-ball either).
Anyone come cross this issue and have a fix? Thanks!
