Recipe removal after unification does not work for IE machine recipes

[wormzjl]

I want to remove for example an IE arc furnace recipe with the following script mods.immersiveengineering.ArcFurnace.removeRecipe(IItemstack output);

The original output item for this recipe is an IE ingot, but the unification target is an RC ingot. The recipe removal does not work if I used RC ingot as argument, only with the item before unification.

However this works pretty well with nuclearcraft machine recipes, I can use unification target item to remove the recipe.

Guess this is related to execution sequence, could this be changed so I can actually turn on Unidict during pack dev? thanks!
