Minecraft version: 1.21.1
Mod loader: NeoForge (21.1.90)
Productive bees: 13.6.7

I was able to add a custom bee through datapack, but it doesn't produce the right honeycomb (it produces the vanilla one) when in the advanced beehive and the custom honeycomb cannot be used in the centrifuge.
I also copy-pasted the datapack (the one about the bacon bee) from the github repository but it doesn't work. Same issues.

I double-checked where I put the files, the datapack structure and the JSON files and everything seems right to me.
I tried different things, but nothing seems to work.

share what you made and I'll take a look

productivebees.zip
Thanks

on 1.21.1 the recipes folder needs to be called recipe

Now it seems to work. Thank you.
Just remember to update the sample datapack.

While I'm here, any way to display just the bee name?

you need a lang file https://github.com/JDKDigital/productive-bees/tree/dev-1.21.0/pb_resourcepack

you might be able to put it in the same datapack

Now everything's fine.
Thank you very much.
