As I reported over at Immersive Engineering's issues page, somehow Quark version 3.4-386 causes IE's ore-to-dust crafting recipes to break. I am unsure why.

Same problem here.

The way I'd manually fixed it was unloading IE's datapack, then reloading it, forcing it to load las. The cause of the problem was clarified on the issue I had linked above.

Yeah that's going to cause problems with all sorts of mods.

It also breaks Integrated Dynamics.
