I have made my own datapack. Rather said I try it. As an example I would like to include the Prosperity Shard from Mystical Agriculture. Unfortunately, the game does not take this. Neither in JEI it is displayed nor can I find it with " coe locate". Am I doing something wrong, or is this not working the way I think it should? Datapacks are still quite new to me :D

Here my zip :)

Your datapack folders are not correct, it must be data/<your pack name>/recipes/drilling/...

Thanks for the hint. I had somehow totally overlooked, although I had checked it several times xD
