I don't want any integrations with nuclearcraft from Tinkers' Construct but they keep happening. I have TC, constructs armory, and tinkers reforged. I cannot find a way to disable it.

There are already configs to disable particular materials from getting tools and armour called register_tic_tool and register_conarm_armor, respectively, but I've also added a new config option for the next build to disable the addition of smeltery recipes called register_tic_recipes :)
