Quoted from Nickbtx:I think it already has on mine. I didn't pay attention to it when I first received it, but the ramp on mine is spread out noticeably and starting to rub on the outer edges of the slots. Maybe they shipped it to me that way, but I can't help but think it's caused by the ball hitting from the back.
Are you sure it's not from the ball traveling anti clockwise while the ramp switch leaver is up, and hitting the thin stern crap and bending it over a certain amount of games played?
