I heard somewhere that Audemon (sp?) cruisers and support ships are supposed to jump in while you're playing the mission. I had never seen them before since I beat the mission quickly, in about 2-3 minutes. So I started again, defeated the Aud fleet in system easily, and then waited and waited and waited ... fast mode didn't seem to be doing anything until about 1-12 minutes into the mission ... then the Aud fleet jumped in, pretty big too. My question - how can it take you 12 minutes to beat that mission? Did the designers screw up?
Phew, long, but there we go!
