This was a solo game.
See turn 17. I drew electricity (7, base) - that was now the only card in my hand.
The 6 pile was out of base cards, but still had Echoes cards.
I applied the dogma of industrialization, and drew several Age 7 (echoes) cards.
I would expect to draw Age 6 (echoes) cards when using industrialization. Is this a bug?
One possible explanation:
Isotropic first checked: "Are there any 6 cards? No? Okay, he gets upgraded to 7", and then checked: "is he drawing Echoes cards, or Base cards?"
