Issue Description:

I have contacted the modpack devs and also done a bit of my own testing, this bug is caused by Armor Toughness Bar (a mod I added that's not included in PO3) and traces back to Hwyla.

What happens:

The game crashes after finishing the loading stages. Crash log: https://pastebin.com/CSEzfZfH

What you expected to happen:

The game to launch to the main menu without crashing?

Steps to reproduce:

1. Install the Project Ozone 3 modpack, version 3.0.38 (latest as of this issue)
2. Add the Armor Toughness Bar mod
3. Launch and wait for the game to finish loading

Affected Versions (Do not use "latest"):

• Hwyla: 1.8.26-B41
• Minecraft: 1.12.2
• Forge: 14.23.5.2808
• Armor Toughness Bar: 2.1
