Older expansions bugged? (Finally came back to this game)

Ever since this patch release I’ve come back to the game late and I’m trying to catch up and when I play older expansions its bugged I think. Idk if anyone cares still but worth a try.
So when I play 1/6 of the Final Doctor Boom puzzle I think its broken and it doesn’t let me use all my mana to get it correct. It kills me with mana left over and doesn’t let me play my final card. It doesn’t let me play the crazed alchemist after the soul repressor, it kills me right after I play the repressor with mana left over.

Sounds like this issue:
