It does not make a lot of sense to use the #forge tagspace when using the Fabric mod. It should be replaced with the common #c directory so that it is easier to add crossmod-compat. It would also be awesome to see the recipes supporting tags for ingredients as well!
This is on latest Croptopia (1.3.0) for Fabric.

I thought I was doing that, the forge tags must've been cached when I was building the jars for 1.3.0. This will be fixed in the next version I release as I re-did my build system again.

Awesome! It has been annoying using KubeJS in order to actually be able to use the same ingredients across mods.

took a few hours messing with gradle yesterday, but now all the recipes will properly have #c or #forge depending on which jar they are in.
