The ceilings seem a little low. I don't know if it is too late to fix this.
The ceilings are 8-9 blocks high, it's a visual perspective which makes them appear low.
I can assure you that theres nothing low about them, i'm capable of piloting a helicopter into the cargo bay, turn it around, fly it down the crew hallway and then land it in front of the elevator.
Looks like a pretty luxury crew bunk. :3
I tried to tell him otherwise how this kind of luxury just doesn't happen for crew, but he wasn't having none of it.
