What I expected to happen was...:
I expected neatherite Ingots to be created with the Anvil. This would make sense, due to the fact that plating or forming alloy, requires heavy "fist" if done without heat.

by professional standards, "Crafting" a neatherite ingot is highly inappropriate. However, this is assuming ancient derbies functions as other ore,

What actually happened was...:
Neatherite is made via the craftingTable. See third step below.

Steps to Reproduce:
1. Mine some ancient derbies, with diamond Pickaxe
2. Smelt it, in a furnace or blast furnace
3. craft it, Gold and neatherite*                     //should be anvil, not crafting table.

Albeit, Neatherite is "f-oo-kin" AMAZING. (Pardon the language)
