The AI cast a Shard of Readiness on its steam machine. Logically, it didn't cost anything to use its ability that turn. Astonishingly, it didn't cost anything to use the ability next turn either. I was watching the card closely, and I knew it didn't play another SoR. I imagine it wouldn't have cost anything the turn after that, but, alas, my corpse couldn't see very well.
Is this a bug? Is it intentional?
