Hello, I made a modpack with a lot of mods and kept getting an error when trying to make or load a save. I removed the metal bushes mod and it loads fine then. It works fine on it's own, though. Here is a link to my question over on r/minecraftforge where I was helped. I go into more detail there.
I was told the datapack for this mod was broken and to make a report here.
The file I used was metalbushesmod-1.16.1-1.6.0.jar

Hey, hmm.. It's funny.. I had the same error with quark somedays on 1.16.1.. I'm not that experienced in modding so it's hard for me to tell what's wrong. I know that the requierd tag thingy: "java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Missing required tags: items:forge:nuggets/copper". should also work fine.

If you add mekanism back to your pack does it break, cause I added a mekanism support to the mod.. maybe I implemented it wrong.

Yeah, actually. I wanted to remove mekanism because I wanted to use immersive engineering instead, and that is when I got the errors. Adding mekanism and it's addon mods back in fixed the problem.

Ok I have the error myself now. It looks like that it has a problem if another mod generates copper..

Ok I fixed it in Version 1.6.1. Have fun!

What other supports should I add? Do you want to have an IE support?

That would be super cool. I personally am trying to make a skyblock quest modpack of my own because other packs seem lackluster to me
