Calling all Spiderman maintenance experts:
Figured I'd start here even though this is a mechanical/maintenance question.
After rebuilding my pop bumpers, I have that annoying situation: left over parts (pic attached.) I can't say it was immediately correlated, but soon there after, sandman would score randomly when the front barrier was down. I've confirmed via config menu that the switches are firing without the ball contacting the sandman switches and no other actions on the PF.
Seems obvious to look for holes for the missing screws. I've searched extensively in the sandman area but nothing stands out. Nor do I remember having to remove screws from that area near sandman.
Any thoughts appreciated. Extra credit I suppose if you know where those screws belong!
