So funny story, Hexcasting was the perfect mod to hide the fact that Serialization Hooks literally didn't work in the first version.
Fixing it came with some breaking changes, which means that once Create 0.5 Fabric/Quilt is out (which includes a newer Porting Lib (which includes a newer Serialization Hooks)) the two won't be compatible until Hexcasting updates.

Should literally be a 2 line update for Hexcasting.

• Current version is 0.3.22 and works on 1.18 and 1.19.
• Ingredient's toNetwork must start with writing a ResourceLocation to the buffer, which needs to be your IngredientDeserializer's ID.

If there's any issues let me know.

out of curiosity, how did we hide something like that lmao

unsealed ingredients have basically the same serialization as vanilla ingredients
not entirely sure but I think they were falling back to vanilla ones instead of erroring
