Hi, I'm running a Forge 1.20.1 47.2.20 server on the server software Arclight (spigot-forge hybrid) and I've been having some crashing issues that appear to be caused by Zeta.

Zeta version: 1.0-14

A normal server log (no crash): https://hastebin.skyra.pw/undefined.swift
Crash reports: https://hastebin.skyra.pw/iciboginib.wasm
https://hastebin.skyra.pw/alewuxatev.wasm
The specific error causing the crash: https://hastebin.skyra.pw/apanijuhuj.scss

Any guidance would be appreciated.

Try with a normal forge server, if it doesn't crash then this should probably be forwarded to arc light

If this still occurs on a normal forge server open a new issue
