Mod crashes on transition between pre-init and init, works in dev env

[Guest]

I am trying to make an addon to add the EnderIO alloys as TE Induction Smelter recipes. If I start the mod in my dev environment, it starts the way it should,

but if I compile it and put it into a normal Minecraft instance, it crashes on the transition between pre-init and init. The code is made to not crash without TE and

EnderIO, it just wont do anything. As dev env I am using IntelliJ Idea.

 

Code: https://github.com/XFactHD/EIORecipesTEInductionSmelter

 

Crash Reports:

    -when trying to add a custom creative tab (works in dev env):
