Minecraft Version

1.20.1

The Issue

I created a datapack using the in-built Datapack Editor and tried putting it on the server.

In server.properties I set the resource pack as required

The animations work, but the hitboxes don't load and only show a fist hitbox. It also breaks all the other hitboxes for weapons which have a custom moveset.
[Also, the hitbox works, it just doesn't display correctly]

However, the issue is fixed when I apply this same resourcepack in my client

EF version: 20.9.4
Forge verison: 47.3.0

Steps to Reproduce

1. make a custom moveset with a custom hitbox
2. upload the resourcepack to the server and make it required
3. join the server and test hitboxes

Fixed in 20.9.5
