Expected Behavior

My friend can see the same animation/behavior as me.

Actual Behavior

Horse Cart animation doesnt work on server as expected.

1. When a player sits in the cart it doesn't show to the other player the same thing, it looks like he is standing in the air above the cart and doesn't move with the cart.
2. When the other player is dragging the cart with the current player in it the cart doesn't rotate and looks frozen, it just translates.

I didn't study the problem in depth, just try it for yourself.

Steps to Reproduce

Run Animania on a 1.12.2 server

Version of Minecraft, version of Animania, Single Player or Server

MC Version: 1.12.2
Animania Version: 1.6.2
Server: Forge
