I haven’t tried a Surge since the lot revamp, but I’m sure I’ve got a couple of Specialist cooking/brewing recipes on Siptah since that. Probably from collecting schematic fragments, or maybe Vaults, I cannot remember. But I’m certain I got at least one duplicate of what I already knew, because I have it in a box in my hidden room, alongside other duplicates I’ve picked up along the way in the vain hope that some day we get a use for them. (You know, we have a latrine now, so I can think of at least one use.)
