Issue Title

I'm running my own modified instance of Infitech 2. The game loads just fine with GT++ 1.6.110, but if I try to update to 1.7.0 onwards (deleting the configs of course) I get a crash related to gtPlusPlus.core.material.ELEMENT

Expected Behavior

Well, it should load.

Current Behavior

Minecraft crashes while loading.

Possible Solution

Steps to Reproduce (for bugs)

Tried every version from 1.7.0 onwards, getting the same result in every case.

Context

I'm trying to get newer versions of this mod to work on a modified instance of infitech 2.

Game Environment

Include as many relevant details about the game environment or modpack you experienced the bug in/on.

• Modpack Name: Infitech 2 (modified, added mainly thaumcraft addons, but I think this crash might be unrelated to those). A third-party pack on the FTB launcher.
• Version used: 3.2.21
