(I'm not good at English, sorry.)
I'm making a modpack with CraftTweaker.
When I updated your great mod "TechReborn-1.12.2-2.12.4.496-universal.jar" a few days ago, your mod's CraftTweaker Support was not working.
Then CraftTweaker showed error log.

Eroor Log
[16:35:31] [main/INFO]: [CHAT] ERROR: SimplyJetpacks2.zs:9 > a method available but none matches the parameters (ZenTypeNative: crafttweaker.oredict.IOreDictEntry, ZenTypeNative: crafttweaker.item.IItemStack, ZenTypeNative: crafttweaker.item.IItemStack, int, int)\nThis is usually an error in your script, not in the mod\naddRecipe(ZenTypeNative: crafttweaker.item.IItemStack, ZenTypeNative: crafttweaker.item.IIngredient, ZenTypeNative: crafttweaker.item.IIngredient, int, int)

ZenScript Sentence
mods.techreborn.alloySmelter.addRecipe(<minecraft:redstone>*5, <ore:ingotElectrum>, <muscariplus:fluxedelectrum>, 200, 600);

I have no idea this issue's solution any more.
I'm looking forward to being your mod better!
