Tchort gate; don't know how to progress (did everything)

[ppg]

I'm at the part where you have to open the gate that leads to the mutagen puzzle, and I don't understand what else I need to do.
I have all the parts (including the correct drive shaft), I already used the grenades, I have the keycard, I have the power allocated to mutagen A and hollow earth and the sufficient mechanics skill. But the only message it shows me when I click the electronic panel next to the gate is "nothing happens"...

Here's my save : https://drive.google.com/drive/folders/1YKVjSKY04eMZaDsuwBWNl36AFI_akHLt?usp=sharing

You need three hydraulic fluid canisters, and you only have two. I've changed the lines to say "one/two out of three" as a reminder.

Thanks, I wouldn't have guessed that this was what I did wrong.

The quest note lists what you need and how much, but considering there is so much stuff to do in DC and thus things can easily be overlooked, why not help the player a bit? Anyway, good luck with Tchort
