In a game against 3 AIs, the Gladiator/Fortune pile ran out. See the attached picture of what the now empty pile looks like. If you don't see the (completely cosmetic) problem immediately: It's the new cost of 3 coin and 8 debt. I don't have the randomizer card for that pile ready at the moment and couldn't find one online, but I'm pretty sure that isn't correct,
The randomizers of split piles have the cost of the top card on them.
I guess the "empty pile" coin cost is overwritten by the game with the version from the top, but debt and potion costs are unaffected.
