I had a ball get stuck dropping from the elevator to the playfield. Another ball got hung up with it. I stuck my magnet on a pole in the lane and was eventually able to retrieve them, it was hard as the lane snakes around a corner. I can't tell if theres mylar there, but the ball drops from the upper playfield down to the lower and I noticed some good dimples starting there. I doubt thats what hung the balls up but maybe in the future. Hard to examine the area, only while looking down through the elevator. Overall my playfield looks really good still compared to some of the later Ghostbusters Ive seen. Maybe more airballs in GB.
