Look guys, if I didn't leave any plot holes in the game, you'd have nothing to make comics about!
(But yeah, if it seems like a concern I'll look at writing/adjusting something to better explain why they want to stay by their shuttle. Of course they do have to stay there, since the whole point of the quest is to defend something outside your normal defenses. One thought is for the crashed shuttle itself to be under attack, or some emplaced nearby immovable object. Or they have to work on the shuttle for a while or something to upload some data or repair it. Lots of options here if it seems important.)
The shuttle is transporting Duchess Chichi, the stellarch's beloved pet chinchilla. Duchess Chichi is quite persnickety and can only be housed in a precisely-tailored environment that your primitive colonists cannot hope to duplicate properly. If the unfortunate survivors should dare to defy Chichi's expectations, the stellarch will learn of it through his psychic powers and punish them.
Genius!
