Not sure if I did anything incorrectly?

I'm confused too. I just tried running the built jars from all 3 OS variations, and they all worked fine with a minimal set of mods. It's still possible I broke something with the action setup, but that crash seems really weird. And removing this mod fixes it?

Hm, it seems I cannot reproduce it. Never mind, then?

I was just able to reproduce it again: https://mclo.gs/bwR4kTa, however a simple relaunch "solved" it, and I can't accurately say it's caused by Thaumcraft Fix so I guess we can just keep an eye on it and keep this issue closed.

I suspect there is some kind of race condition between forge and one of your other mods messing with ingredients (such as trying to construct an instance of one while forge is in that loop), but I don't know if that's actually what's happening or which mod would be doing it.
