In trying to make a recipe using an LP input I got the following error in my crafttweaker.log:
https://pastebin.com/XGBDmkzY

Said recipe is
bmt3auto.start().duration(200).inputItems(minecraft:stone).inputMana(10000).inputLP(1000).outputItems(bloodmagic:slate:0).buildAndRegister();

The mention of 'EMC' confused me so I went and looked at the recipe source code, which reads:

public RecipeBuilder inputLP(long lp) {
return inputEMC(1, lp);
}
