The removal of Ancient Warefare has caused a couple of issues... one that results in a crash. Magical Crops essence did craft AW steel.. obviously with the removal of that mod it no longer does (Im guessing I lost something like 20k steel ingots?)... However, when placing the Magical Crops steel essence in the 3x3 crafting grid a recipe for a "steel ingot" still shows... Item ID -1 However when attempting to remove this item from the crafting table... instant crash. Might be worth switching the recipe to a different steel ingot. Cheers to Ken for the screen shot.
