I receive an "Improper or lacking ingredients in crafting station" error when I attempt to use a blacksmith hammer on an anvil that has a Template for Alchemical Arrowheads, Steel Ingot, and Steel Alchemical Arrowheads. When I remove the Steel Alchemical Arrowheads I don't receive the error anymore, and I can continue to craft more arrowheads.
The bug persists with bolts too, but the Alchemical Bullets work fine which leads me to believe something here is unintended.
