I can't manage to get ContentLib RecipePatches to work, I tried to copy the example from the docs, but the recipe for Solid Biofuel stays unchanged.
SchematicPatches work just fine (in fact I made the milestone for Solid Biofuel free so that I could test it). Here are the example given and the change I was trying to use (neither works) and the working Schematic.
I just figured out the problem, when I created the file automatically it used LF instead of CLRF that it uses when I create it manually, that's why it failed and the issue was inperceptible.
