Scion of the Deep Duels Treasure Does Not Count For Achievement

There is a Priest achievement called “You’re Ghuunna Be Sorry” that says “Spend X health to play cards as a priest.” There is a Priest signature treasure in Duels that is called “Scion of the Deep” which says “The third spell you cast each turn costs Health instead of mana.” I used this card and effect in my Duels run but it didn’t count the health I spent on my third spell for my achievement. Is this an intended result or is this a bug and can this be fixed? Thanks!

Exact same issue, got it yesterday. Think it’s a bug

Came here to report that this issue remains unresolved.

The Priest Duels card Scion of the Deep features card text that reads “The third spell you cast each turn costs Health instead of Mana.” This is indeed how the card functions, but Health spent via this card does not count toward the You’re G’hunna Be Sorry achievement. Based on the text for the achievement, which reads ‘Spend 10 Health to play cards as a Priest.’, it would seem like Health spent via Scion of the Deep as a Priest should count towards the achievement.

I am encountering this issue as well.
