Both reply’s helped a lot, I am able to at least see some progress but still not quite getting there. so I have made child blueprints of the core, adv rifle ammo, and the engram for adv rifle ammo I also changed the names around a bit so I could see what’s changing a bit easier and I get the new engram and I can learn the new engram but now that new advanced rifle bullet engram does not show up in the fabricator so I cant get any further. Any idea why it wouldn’t show up in the fabricator? I couldn’t see any lists of engrams on the fabricator or the fabricator storage and the primalitem still has the fabricator inventory as a required inventory component
