Keep getting crash pop ups whenever buildcraft is used.

BuildCraft version: 7.99.21
Forge version: 14.23.5.2808
Link to crash report or log: https://paste.dimdev.org/qibiqadine.mccrash
Singleplayer or multiplayer: Multiplayer
Steps to reproduce: Use any buildcraft items in world.
Additional information:

That's odd, it implies that a pipe sent an update packet before it sent out a render packet...

I'm honestly not sure how to debug this, how many buildcraft pipes do you have placed in the world?

I had a wood pipe, a void pipe, and one engine. The next time the server was restarted, the issue started happening.
