Stone Joker is the last one left without Gold Stake Sticker. It is discovered and has Green Stake Sticker.
All other Jokers missing Gold Stake Sticker would show up multiple times each run until they were completed, even when only 3 or 4 Jokers were left with no Gold Sticker. There must be RNG manipulation to make them appear more often.
But Stone Joker just won't show up. It's been +10 Gold clears, and one run had +$200 of rerolls. Never seen this Joker once. All these runs have at least one Stone Card in deck.
Is this Joker mistakenly not affected by RNG manipulation? Is this a bug?
