Quoted from EStroh:Check the slings for the ball.
That was it! Thanks a million for saving my sanity.
Here's what I think happened:
Ball was sometimes getting stuck in left side in-lane.
I loosened and readjusted the plastics and posts in an attempt to fix the issue (which it seemed to do).
In the process, I knocked the top off one of the leds.
I removed the LED in the hopes that I could fix it (I could not)
I then had a hole were the LED was.
And I mistakenly had the sling kicker on the OUTSIDE of the rubber.
I think both those combined made it much easier for the ball to make it past the rubber.
And then nestle between the two posts and remaining LED. Even looking for it, it was very hard to see!
