I'm not sure what's going on with mine now.
I've only played a few games since the play field swap, so I'm slowly working out the kinks with that.
I just played a game and locked 3 balls. When I shot my 4th ball into the "Release" lane and the upkicker, it releases the other 3 balls, but holds that 4th ball on the upkicker. After draining all 3 balls, it finally kicked it up.
I then replicated this whole thing with the glass off and it did the same thing, but instead of finally kicking the ball up after draining all 3, it just kept giving me another ball in the shooter lane. So, the game never ends.
I had to power off and back on, and when I did that, it kicked it up.
Any idea what's going on here?
With all those lights flashing, I didn't even notice this issue at first. It was only when I shot a ball up there to "land" and it can right back down because the upkivker was already occupied.
