Should be fixed as of 0.6.1

I'm guessing the Curseforge/Modrinth mods are still reviewing it, but I'll test it when it pops up. Also, thanks for the quick reply!

The fix I implemented was related to a Mixin into my own class, which only applies when Lithium is present.
It implements getters for the size and the contents of the chest inventory using Lithiums interface (LithiumInventory).
For some reason one of the fields was not present when running the game normally (this worked fine in my dev environment), so I changed the logic to grab them directly from the chest itself using some small hacks.

I have started also releasing Decorations here on GitHub. You can see them in the Releases tab: https://github.com/Noaaan/MythicMetalsDecorations/releases

Oh, ok. That's super convenient. Also, confirmed, definitely working now. Thanks for the quick fix. Out of curiosity, what was the issue? Was it a conflict or something?

Oh, gotcha.
