Forge version: 14.23.1.2560
Twilight Forest version: 3.5.263
Link to crash log: https://hastebin.com/jihocisisi.sql

Steps to reproduce:

1. Open to lan, with another player
2. Go to forest, equip mekanism armored jetpack on both players
3. have the host kill the naga, but the other player not
4. both players fly toward lich tower
5. when non-host sees progression particles (yellow squares), should crash for host with above report

What I expected to happen:
No crash
What happened instead:
Crash

This is on mekanism's end

at mekanism.client.render.RenderTickHandler.tickEnd(RenderTickHandler.java:135)

Issue is on Mekanism's side.
