I know that this forum seems to concern actual game-breaking or glitch bugs, but, I noticed that there's no place to report item copies. As such, I figured that the following problem is a massive *bug* in and of itself, considering how many people likely have one, the other or BOTH, especially if changes to either must be made while so many copies of both are already out there. I've recently made the discovery that Flax's Thirsty Vial and Wuuna's Vampiric Shroud are one and the same in terms of the cards they add to one's deck.
They're just re-skins for some special occasion in the past (apparently something @Flaxative did). You'll be seeing them in the upcoming Halloween shop as well.
Yeah, Flax's Thirsty Vial is a promotional copy of Wuuna's that was added to the game as a thank you to me long before I joined the dev team. Someday I'd like to change it to be different from Wuuna's, but this isn't a bug per se.
This is amusing to me, since I have (IIRC) five Flax vials and zero Wuuna's shrouds. edit: up to six vials now :0
It basically doubles your chances of getting a very good tokenless vamp item, which is not a bad thing.
