Quoted from Jeffswack:First issue that I'm having is surrounding the building mech. The top floor building gate that holds the balls isn't coming up enough to release the ball. It moves freely with my hand.
Looks to me like you're building is not going low enough. I also see a stuttering towards the end as if something underneath is blocking or impinging the mechanics. Lift your playfield and examine the building mechanics for any foreign objects along the glide path. Make sure all screws, bolts and nuts are accounted for and secured.
