Quoted from pintechev:
I bent the right rail out just a snug and it’s much less frequent now. When it hits his feet, it’s often going to the left flipper, so, while it might not be exactly as Gomez designed, it’s not draining here.
Would be good to hear from original owners if this happened. I can’t see how it wouldn’t. A straight shot down should avoid Frank, but if it’s bouncing off the rail, there’s no way that I can to completely avoid it.
For what it's worth, my original MB also does this - I have gotten to be a master nudger when the ball circles the right side. it never seems to hug the ball guide the way it seems to be intended. But fear not! I just put up a 500M game today. Personal record baby!
