That’s some serious bad luck. I’ve bought many nib games over the last several years from stern, cgc and spooky and I’ve had minimal issues. My distributor has immediately sent his tech over and/ or ordered the needed parts. I’ve never had to pay for these parts either they have all been warrantied. My distributor is nitro pinball btw.
Maybe I’ve just been lucky but I’ve yet to have a major malfunction or playfield issue yet. I even had no ghosting on my gb premium!
