I was mixing them with standard units.
also my leech starships arnt taking over anything either... Arnt they supposed to mark multiple targets (up to 40 if i recall correctly) and when the marked ships explode they become yours?
Or are the leech ships maybe not piercing through the armor and therefore not causing any damage?
edit: started a new game and made some leeches. they were working. Maybe the ships are just getting destroyed right after being reclaimed in my other game
edit again: *sigh* I sent 3 leeches towards a frigate.. They fired at it multiple times and damaged it. It was then destroyed by a different ship and definitely didn't become mine..
I'm confused
