I'm really at my wit's end with this puzzle. I couldn't find a manual for repairing the gate, but I managed to find a hydraulic control valve in Tithonus, a hydro-pneumatic accumulator and a couple cans of hydraulic fluid in Warehouse Block 2, another can of hydraulic fluid in the elevator cavern past the burrowers down south, and about a hundred different hydraulic pump drive shafts, including what I believe to be the correct one, the HS-89 model, which I found past the worm labyrinth. I've got 5 psimorphic biocide grenades processed from the heart of that stupid root thing that took about 50 turns to kill, I've got Maria's keycard from Caerus Residential, and I've got a red AI core from Arke. As far as I can tell this is everything I need to open the gate.
But I can't figure out how to do it. Clicking on the panel tells me to get a manual that I don't know the location of. Installing the core in the bot prompts it to call me an imbecile a bunch of times and asking it to fix the machine tells me it needs components, and that they should be placed close to the machine. What am I meant to do? I've tried dumping them on the ground in front of the panel, stashing them in the empty canister... am I being incredibly dense or is the mechanism for doing this seriously obtuse? Or am I missing something?
Edit: Nevermind. Needed the manual, as I'd suspected I might.
This damn fetch quest.
