While cleaning up, changing to Titans, replacing slot target and magnets, and some other stuff I found what looked like the end of a screw slightly sticking up out of the playfield behind the upper left flipper in the ball path to the camera shot. After removing the flipper mechanism it turns out it is roll pin. It can't be lowered into the playfield as it hits a flipper coil bracket screw. Pics are after I pushed it out some.
Is this meant to be there?
