As in the title - the caravan with a vehicle returned, but I can't seem to find the way to order the colonists to unpack it, nor do they do it by themselves (like they do with pack animals).
I could dump the cargo on the ground, but then it'd be deteriorating, unless I micromanage for the colonists to pick it up immediately. (or build a garage, but with the way the vehicle handles, I find parking it in a specific spot somewhat tricky, so I'd rather not have to)

So yeah, is there a way to have the colonists unpack it?
