I have no idea how ATM9 did it, but i can't seem to find a way to remove the seed drop from mystical agriculture, i tried using kubejs,lootJS none seem to affect the seed drops what to so ever, is this a bug?, is it cucumber fault?, and if both are no, how can i remove the seed drop from mystical agriculture crops leaving only the essence drop

Are you referring to the secondary seed drop? If so you can disable those globally in the config, or per crop/crop tier using Mystical Customization (docs). If you mean that the crop should drop 0 seeds when broken then I don't think that's possible currently.

I'm going to close this due to inactivity. If this is still an issue on the latest version you can reply here.
