Describe the bug
ServerCore prevents the Vanilla Tweaks Armored Elytra datapack from combining items, still allows separation on grindstones. There are no logs that I can find that explains why this is happening, I found out by uninstalling each mod one by one to see what would solve it and everything but ServerCore passed the test.

Reproduce
Steps to reproduce the behavior: Install ServerCore, Install Armored Elytra datapack, attempt to combine elytra and chestpiece on an anvil

Expected behavior
Elytra and Chestpiece to combine when thrown on an anvil
Versions -Latest is not a version!
ServerCore: 1.2.6
Minecraft: 1.18.1

Mod incompatibilities
Just gonna list all my other mods but I don't think any are causing issues.
Lithium
Starlight (Previously Phosphor, but was broken on both mods)
Universal Graves
Carpet
Carpet Extra
BlockBot

Some datapacks seem to require the spawn chunks to be loaded to function correctly.
Set disable_spawn_chunks in servercore.toml to false, that should resolve those issues.

I'm going to be turning this off by default for future updates aswell, because of its potential to break datapacks.
