if you want to change a recipe (ex: 4 barks crafted instead of 3) this doesn't work and will always craft the vanilla recipe unless you disable the vanilla datapack (which is not very handy if you just want to change one craft)
expected:
craft the recipe of the top-most datapack if there are conflicts
Cannot reproduce, make sure you set the data pack to load after vanilla.
