Issue description:
It could be me, but I can't seem to create a new casting recipe using modtweaker. Removing casting recipes and adding alloy recipes worked fine. Maybe I'm just calling the function wrong, also I didn't really know what to put at the variable for the cast.
Did I do something wrong? These are the commands I used.

Casting.addTableRecipe(primal:brass_ingot, tconstruct:cast_custom:0, liquid:brass, 144);
Casting.addTableRecipe(primal:brass_plate, tconstruct:cast_custom:3, liquid:brass, 144);

Versions:

• Minecraft: 1.12.2
• Forge: 14.23.5.2854
• Mantle: 1.3.3.55
• Tinkers Construct: 2.13.0.183

The brass ingots are from PrimalCore version 0.6.105

We're not involved there, check with modtweaker. I don't know what modtweaker does with this.

Ok thanks!
