Stuttering Player Movement with 3+ Players on Server

[MinecAnton209]

Describe the bug
When playing on a server with the Mo' Bends mod, player animations become stuttery and unnatural when 3 or more players are simultaneously in the world. However, if there are only 2 players on the server, animations work correctly and smoothly without any noticeable hitches.

To Reproduce
Steps to reproduce the behavior:

1. Start a Minecraft server with Mo' Bends and other mods from your modpack installed.
2. Invite two or more friends to join the server simultaneously.
3. Wait until there are 3 or more players on the server.
4. Observe the movement of other players – it will appear stuttery.

Expected behavior
Player movements are expected to be smooth and fluid, without any stuttering, regardless of the number of players on the server, similar to how it behaves with only two players.

Context (please complete the following information):

• Minecraft version: 1.12.2
• Mo' Bends version: 1.2.1 - 19.12.21
• Other installed mods: The modpack contains approximately 60 mods. (Please list the main or most likely conflicting ones if possible, or state that the list will be provided upon request.)

Additional context
The problem does not occur when there is only one or two players on the server. This might indicate a conflict with other mods that only manifests under increased server load, or a performance issue with Mo' Bends when animating a larger number of entities. We are using around 60 mods in our modpack.
