Bug Report

Observed Behaviour
I was updating mods on a private server that I wanted to host for some friends of mine when a crash occured when trying to launch the server. I narrowed it down to Tetra after having only that and mGui as the only ones left in the server's mods folder. I tested making a server on my personal computer and it had the same result.

Crash log:
crash-2020-05-20_22.42.47-server.txt

Expected Behaviour
The mod should load and the server should begin loading the world.

Minimal setup needed to reproduce
Only Tetra and mGui was included in the mods folder at crash. Config was not touched.

• Forge version: 1.15.2-31.2.0
• Tetra version: 2.6.0 to 2.7.0
• Tetra configuration: default
• Other mods: no

Steps to reproduce
Make a forge server. Include Tetra and mGui as the only mods in the mods folder, and attempt to launch the server.
