CRAFTBOOK-3344 - Reported by kungkong

No matter the recipe, the shaped and shapeless crafting yield the same error in console. Furnace crafting works fine.

Note that this happends even with just the default "Shapeexample" and "Shapelessexample" in the file.

Due to changes in spigot in 1.12, any reload functionality is incompatible with anything that adds recipes.
