Bug Report

Observed Behaviour

Was playing around with Tetra in singleplayer for a while. Decided to make a small server for it to play with a friend, but I was greeted with This Crashlog.
Expected Behaviour

I expected the server to launch as usual, of course ;p
The mod doesn't crash in singleplayer.
Minimal setup needed to reproduce

• Forge version: 1.12.2 - 14.23.5.2836
• Other mods: Line 85 in the crashlog has an accurate modlist, however I suspect they are unrelated
• Tetra configuration: Unmodified.
• Tetra version: 0.27.0 (there's no field for this in the template, you should consider adding one)

Steps to reproduce

Make a dedicated server with Forge and Tetra 0.27.0.
Run server.
Crash in Init.
