hi, I'm encountering this error when I start a modpack with Jewelrycraft 2:

Error, tried to add subtypes of item item.DDSWL2
Item is not added in the list.

because of these errors the client takes too long to load and start, I already know which mod is causing these errors with Jewelerycraft 2, but I don't know how to avoid the creation of these subtypes. There's a way?

Oh boy, uh... sorry for late response. No, there is no way to do it. I also stopped working on it a long time ago, so if I were to ever fix this, it would probably be for a newer version of Minecraft.

Maybe dor 1.12.2.
I miss a mod like this in my modpack.
I rly like it.
