Starships are always in danger of acquiring a leak and thus endangering the crew. IMO the ship could use a really good and solid wall between the cargo hold and the crew quarters. That way you could intentionally open the cargo hatch to get rid of some non-robot invaders or to take out a fire. A single-wall doesnt fulfill that requirement well enough IMO. Also: Is there a hatch so your crew can get outside for some repairs in space?
