About this Mod

Minecraft has a bug where when an entity exceeds 3.9 blocks/tick it doesnt display correctly on the client.
It not only will have the wrong speed, but due to improper math by mojang its direction is also falsified.

This mod adresses that and correctly syncs the velocity to the client.

THIS IS REQUIRED ON CLIENT AND SERVER.
