Hey can you give me an example or a more detailed explanation it would help a lot.

For now all I'm doing is a custom recipe in a normal 1 input, 1 fuel slot and 1 output furnace

So I have make a custom Furnace lock called "Alloy Smelter" and I want to make a recipe for it but i don't know how I've seen that there is a "FurnaceRecipe" class but I'm not sure how to use it. Can someone help point me in the right direction, thanks (Also I'm just wondering are 1.15.2 forge questions allowed?)

I am try to make my on mod but every time I try and join a world the game crashes. Here is the crash report: https://pastebin.com/zRMY5Ta5 It the crash report it says "java.lang.RuntimeException: Why did the advancements not load yet?!" but I haven't made any custom Advancements yet!
