An extra enemy was placed on a ring around its starting location, trying
one spot per ring, and checked only against walls. When the 8 tries failed
(tight corridors, the Maw's interiors) it went on the starting location
itself, on top of the squad's own actor, and nothing stopped it landing on
another starting location's actor a metre away.
Now every spot of each ring is tried (a ring holds more spots the further
out it is), and a spot needs ground under it, no wall in the way and no
biped within 0.6 m or vehicle around it. A starting location with no room
passes its enemy to the squad's next one, and with no room anywhere the
enemy isn't placed. Dropship riders released beside the ones who jumped
out are spread the same way.
