This mod adds a recipe for Iron Hydroxide, which was missing.
For some reason your mod removes the third motor casing 1 recipe, the one that uses non expendable molds
I think I found the problem, it has to do with tech angels iron smelting 3 not unlocking that recipe
I fixed it, just need to add the following code below line 64:
{ type = "unlock-recipe", recipe = "angels-casing-iron-2" }
