Hi, I think there's a bug, Augmentium isn't made using any machine. In Factoriopedia, it doesn't have a "Made by" section in fact.

The only machine that shows an Augmentium recipe is the Centrifuge, but it just says that it cannot be crafted there. I have none of the optional mods btw, only Augmentor.

A screenshot you might find useful.

Can you give me what other mods do you play with ? because it is made in centrifuge.

I run 100+ mods, but only one affects the Centrifuge, and I've already tested disabling it - Plutonium Energy.

In fact, I started a new game with just Space Age, Quality and Elevated Rails active (and obviously Augmentor and Augmentium) and the result was the same

And I know it's not meant to be like this because when I search Kovarech on factoriopedia it tells me it's made on the centrifuge indeed.

My understanding of factorio modding is very superficial, but I went and took a look at the prototype/recipe code and when it comes to the recipe that doesn't involve detecting if other mods are present, it only says this

local catcraft = "centrifuging"

I've tried to check other recipe mods for references to something similar to this, and have come out short. Is it possible that this is what's causing the issue? Maybe the mod is accidentally dependent on one of the optional mods to actually allow the centrifuge to craft augmentium.

Because it's like I say. The recipe IS at the centrifuge, it just says "cannot be crafted there" when clicked, and the symbol's background is red, similar to other recipes in Space Age that are of a certain category but require a specific machine.

I think I confirmed my suspicions. This is with adding Nuclear Science (So Factorio Base + DLC + Augmentor + Augmentium + Nuclear Science).

It seems that it's a simple case of Augmentium not being assigned as allowed in the Centrifuge if you don't have any of the optional mods.
