Currently building the predator prec on my engineer and can’t get 2 items listed, I have all the others. The two items are:
-Scarlet’s Prototype Mechanism (can see it on the desk but is untargetable and you cant interact with it.
-Decrypted Weapons Research (I used the console after finishing the puzzle and chose Decrypt weapons research, and it did nothing and exited me out of the console menu)
