Playing on PC.

Played in an Edge of Eternities Alchemy draft, won 6 Edge of Eternities Alchemy packs. On opening the packs, one of them gave me a copy of Glimmer Hoarder as my rare, which is a card from Duskmourn Alchemy; users on the MtG Discord server say this is a bug.

Update 29/8/25
Since posting this bug, I've had it happen twice more - once getting an Outlaws of Thunder Junction alchemy card in a prize pack, then having the rares for two of my prize packs in a separate draft be replaced by a Tarkir: Dragonstorm alchemy card and a Bloomburrow alchemy card, screenshots and logs of which I've added to the ticket.
