Got my shipping notice from RGG today that my replacement cards are in the mail. Very quick turnaround time.
To bring this to a close:
1) the shipment, due to my error, couldn't be deliver and was returned to RGG
2) I offered to pay for them to be re-shipped - RGG refused and shipped them again at their cost (which, again, was due to my error)
3) the cards arrived a few days ago while I was out of town
4) RGG replaced more than I asked for (they replaced the entire "brick" of cards, even though I didn't need replacement Events, etc. since it doesn't matter if they're off-center)
5) They threw in a copy of the Prince promo
A+ customer service here.
I obviously still have my problems with what led to this issue in the first place, but my set is now fixed and RGG is responding to this issue in nearly the best way I can imagine (fixing the printings, replacing everyone's stuff).
