Has the thought crossed anyone's mind that if the UA indeed is the cause of stations infection then selling them at a surface starport then will do the same plus potentially corrupting the planet as well? Maybe random not traveled ports need to be tested and in different types of worlds too just to see what happens. Who knows that might trigger a system wide quarantine and cause "things" to grow? The Tiberium point made me think of it but metal life forms make me think that high metal worlds should be the likely candidate for this sort of event, after all we hit in the past on the observation that UAs seemed to prefer systems with a lot of metal.
