This is probably an issue with NEI, but I figured it might be something to do with the way ore dictionary is configured in this pack. The advanced blast furnace from Immersive Engineering has a recipe for pig iron, using vanilla minecraft iron. That is the only option that shows for input. The fuel scrolls through options appropriately. Despite this, I've confirmed that TFC wrought iron can be used in the blast furnace.
Thanks for curating this pack.
