I see recipes inside the mod jar but there are none appearing in-game in JEI or recipe book, and the described recipes in the jar dont function

MC 1.21.1
Fabric 0.16.7
Mighty Mail 1.21.1-1.1.2
Framework 1.21.1-0.9.3

Found it's because all of the recipe .json files use "item:" in the result field when it needs to be "id:"

is there a way to fix it on your own and put it back in curseforge?

Yeah sorry for the late reply

You can make datapacks to create / replace recipes.

Here's the one I made back then, though this is from November 2024 so I can't guarantee it's up to date. If you need to update it it shouldn't be hard to dig into this zip and see what I did. I just matched the mod's original recipes but used "id:" in the result field instead of "item:"
