Crafting the Tek Rep.
So I'm playing on the Win10 Xbox version of Ark. I am playing single player, with the single player setting enabled on The Island. Now the problem. I have the Tek Rep. engram, but where do I craft it? I already know that they can be crafted from the obelisk and supply drops, or so I thought. I have been to every obelisk, have checked countless different supply drops and loot crates. Nothing lets me craft the Tek Rep. Now when I disable the single player setting i am able to craft it at the obelisks, but not the supply drops.
