Unfortunately, doors are so broken I got stuck. Got to the long hallway, walked down, opened the keypad door, hopped down. I got to the dark area and got the "Open Door" prompt but nothing happened when I tried to open it.
All doors are kinda buggy, they'll open but not close properly. And then if they do close, you kind of have to try and open them a few times, and it takes like 3 seconds to trigger when it does work.
