Confirming the issue (seen below) but was able to load mod and have it function in-game with beta.4 from Curseforge.

I get the exact same error. Looking through TenzinLibForge.java, it seems like this error happens when register(String id, TLibForgeMod mod) is called before initialSetup() runs.

Turns out it's related to the dependency lists in mods.toml.

This block:

[[dependencies.strawgolem]] modId = "tlib" mandatory = true versionRange = "*" ordering = "BEFORE" side = "BOTH"

Should look like:

[[dependencies.strawgolem]] modId = "tlib" mandatory = true versionRange = "*" ordering = "AFTER" side = "BOTH"

updated to be "AFTER" in mods.toml for newest release 2.1.0-alpha.

lmk if this fixes it!
