I Think it is because you used the alchemical construct and not throwing in the stuff yourself in the crucible I had the same problem using Botania Halo thing and making Black Slates from Blood Magic via right clicking on the recipe in the ring, it didn't count the last two. Try making it without the alchemical construct, I think it doesn't recognized "you" crafting it that way. I made one just fine before the update in the crucible.
