Paralyzed units should not be captured on missions where we need to evacuate our operatives. Currently they are magically teleported to confinement on mission completion.
This would also make reworking citadels a good idea. Changing the evacuation mission requirement to secure the area, and having reinforcements stop after the scylla is dead or while it is paralyzed/mind controlled. The entire contents of all goodie huts should then be acquired on completion, which would probably make reducing the average number of goodie huts a good idea.
Units mind controlled upon completion of non-evacuation missions should be captured, and we should be able to evacuate (thereby capturing) mind controlled units (removing their WP maintenance costs and no longer preventing the recover action of their former controller).
