This is really starting to worry me. This type of problem should not be happening so early. Ive got several pins with thousands of plays and no wear like this. I inspected mine really close and im all good so far but I only have 288 games started and 169 played. ( my kids like to start games and not finish them ).
I love my Wozle but all these concerns are really starting to worry me. My drop target still makes a crazy amount of noise every 3-5 games and I've played with my lockbar for hours and it still doesn't work properly. My crystal ball doesn't work every 10-15 games and I've had a few light lock ups. That said, every time I turn it off and restart it, its all good again.
If a piece of playfield popped off like this on mine, as much as the whole family loves it, that maybe the last straw.
