Smelting, Blasting, Smoking and Campfire cooking not working in 1.15.2

[John147GHN]

As the title says, it's not possible to create Smelting, Blasting and Smoking recipes as of 1.15.2. You can "create them" but the recipes won't even appear in the actual game.
I checked and I can do these recipes using forge. I made a simple "smelting a chest gives a diamond" recipe and it doesn't work in my mod's workplace nor creating a new workplace with this single recipe. Any help is greatly appreciated.

I know the cause, but I don't know how to fix it. I need to rewrite a section of th mcitems.ftl file (used to write the right code when we selecte an item, a block or a modded thing). I'm still trying to change the code, and then many things will work (and I will be able to release a new dev version).

I found the cause. It will be fixed in the next update.
