I asked this question trough the official help channel previously and have not received a response so I am going to ask this here.

One of the rewards for the first scenario in Guardians of the Abyss is John & Jessie Burke. This card is meant to represent 2 named characters and therefore it theoretically should be a unique card however it isn't. Should this have errata to make it unique?

Of note this really only matters if someone is playing as leo anderson ( can mitch keep them around) or if you run it as a side scenario in the dunwich legacy (blood on the altar).

This should be unique

It is not the first time an unique symbol is ommited on a card (for instance on the LOTR LCG hero Quickbeam)

Love how they kept the name, trait, flavour text and even what the card does (more or less) for this card the same as the original Call of Cthulhu card

Nice, nostalgia

Perhaps "John Burke" and "Jessie Burke" are just common aliases among whatever agency they hail from. You know, like that theory where "James Bond" is really a succession of different MI6 agents.
