Nickel ore (and zinc ore from brass tacks) don’t have SE matter fusion recipes like all other ores. SEK2 adds matter liberation recipes, and they don’t have those either. Since zinc and nickel are added to core mining and scrap just like all other ores, this feels like an oversight?

Secondly, SEK2 changes the way matter works compared to K2 alone. In SEK2, matter to ore recipes require basic matter stabilizers that are added by SEK2. Zinc and nickel ore don’t adhere to this, which I feel like should be fixed.
