The Issue

Resourcepack/Datapack with custom animations made with in-built Datapack Editor breaking hitboxes in Multiplayer

This pack breaks the hitboxes of weapons that have altered movesets, including itself.

For example, the golden Greatsword is completely fine, but netherite greatsword has default fist hitbox. However this bug seems to be only client-side, and the hitboxes are the appropriate size, however they look like the fist hitbox.

This pack simply gives iron Greatsword new animations.

EFACA.zip

And it breaks all the hitboxes of altered weapons from a pack in our server which changes certain weapon's movesets [Netherite Greatsword, Bokken, Diamond Axe... etc] and all of their hitboxes appear as a fist.

However, when I take the same resource pack and apply it to my game:

Then it fixes all the broken hitboxes. But this means the "required resource pack" feature doesn't work.

EF version: 20.9.4
Forge version: 47.3.0

Steps to Reproduce

1. make a custom moveset for a weapon
2. add it to multiplayer server [resource pack required]
3. download the pack
4. check hitboxes
