They are looking into it, I can tell you that many of the pictures are in completely different light, angle, ambient light, mm vs mmr, etc and so it's really hard to compare one vs the other to get a clear picture of any differences. But I did make sure Doug Duba at Chicago Gaming was aware of the topic, and he will look into to it. I've also alerted Stern production manager of it as to see if they can see it, apparently whatever is going on is not obvious and not sure under which light or conditions, etc.
Hey Rick, thanks for the response. A great way to check for them would be to look at the "Jackpot" and center line of inserts leading up into the castle and compare them to the others (Catapult, Joust, Peasant, Castle...etc. The difference is obvious even without light underneath. They are faded/transparent when the others are opaque.
