Other information that you think might be useful:

I tried adding many recipes, none of them worked.

The example given:

minecraft:awkward&minecraft:dye,3=minecraft:strong_healing

does not work.

When i set the itemstack to an invalid item, the game does not crash, but the recipe is not added.

While this was observed on an older version, it might potentially apply to newer ones. I can't update to verify it though. It would be really cool to actually use a magnet provided by another mod I have rather than using an iron ingot for a potion of magnetism.

It's probably a forge update that broke something, that's my best guess. I'm in the process of rewriting the mod anyways for 1.12+ so I'm not even gonna bother seeing if it's a bug or not in more recent versions for now
