I kick Dwayne Badluck from my ship into a hostile environ (at least for his race). It takes roughly a day (from what I remember, I haven't tried it in quite some time) to cross terrain into a "civilized" grid.
Does him becoming unconscious stop movement to another grid? ( I ask because the Problem Centre may become swamped with " I'm stuck" questions. I went exploring my first few days, and this could become a nuisance)
