Describe your issue

For the Foundry I have set the Oreyield to 3 Ingots/Gems and the Byproductyield to 1 Ingot/Gem and that is working as it should, but in JEI it only very few ores with the correct yield wich are the Copper Ore(Regular/Deepslate), Raw Copper and Block of Raw Copper and all JAOPCA added Recipes, with all other ores, raw metals and blocks of raw metals showing a 3x the Byproductyield, despite giving the correct yield on melting, the Issue persist, when testing only with Mantle, Tinkers Construct and JEI

Crash Report

no crash involved

Other mods

Mantle, Tinkers Construct, JEI (10.2.1.283)

Reproducing with only Tinker is not possible, since JEI is required to show the Recipes

Tried reproducing with just Tinkers?

No

Performance Enchancers

None of the above

1. Unrelated issues should be on their own ticket
2. That is intentional. It's a byproduct, it's your job to ensure there is space

well ensuring that there is enough free space is very difficult without comparator support

Did some digging into this myself, the problem fortunately was visible from your config file without me needing to dive into your mod list. You boosted regular ores to 300% their regular output, and JEI is using that rate to boost byproducts displayed, it should only use that rate to boost the primary output for the foundry.

The thing that threw me off was you insisting that copper was correct. I strongly suspect that copper fits the same trend as the rest of the ores, you just misunderstood that copper ore has 1/3 of the byproduct.

It's not clear to me what the issue is here, can you provide screenshots of some example affected recipes? Is the correct value shown when you try crafting it? Sounds to me like a misunderstanding of the ore rate config

There is absolutely no reason copper would work while others would not, however copper does have less byproduct than the average ore, thus suggesting misunderstanding.

This does sound a little like a bug that was fixed in 3.5.1, its literally impossible for the byproduct rate to affect just JEI after that version as the byproduct rate is only considered during JSON parsing.

when melting the ore in the foundry it produces the correct amounts based on the config and after checking again in fact Raw Copper is the only ore showing the correct Recipe
Here an Example of the incorrectly shown Recipes with Raw Iron:
JEI shows me melting 1 Raw Iron in the Foundry gives 3 Ingots of Molten Iron + 3 Ingots of Molten Nickel,
but when actually melting the Raw Iron in the Foundry it gives 3 Ingots of Molten Iron + 1 Ingot of Molten Nickel

Can you provide a screenshot of the mod list from the main menu, or a screenshot of your mods folder?

Also, provide your tinkers config file.

Did you manage to reproduce with fewer mods? If you reproduced with just Tinkers and JEI, show me that mod list instead of a list of 100+ mods.

Also, let me reiterate, you describing that copper is correct and no others are makes no sense. Please, try melting copper ore to verify that you see the same value in JEI as you get when melting. Copper ore normally has 1/3 of the byproduct of other ores, the rate is a multiplier, not an absolute value

Of course you are right with the copper ore, I forgot the increased yield of copper ore compared to the other ores and while confirming this, I found another unrelated issue:
when melting things in the Foundry, that have byproducts and there is not enough free space for the full amount of the byproduct, the amount of byproduct, that doesn´t fit in the Foundry, gets deleted

Fixed in 3.5.3.63
