I can imagine a seller having the game set up in their home for a few years, cleaning it up, taking photos of it and not remembering there was some non-visible damage. You don't normally put the head down when taking photos or selling the game, the only time I take the head down on my games is if they are being broken down for a show or to sell. But, upon noticing it when packing it up, it would have been cool if they said something and offered to knock $100 off the agreed upon price. Luckily it's inside where you will never see it.
