I must say, the AI instead of wasting so much money on my bounty, it has a hard time building up a decent strike fleet to even begin to make me worry. Infact it seems to send ships one at a time to their death.
Instead of a huge fleet, I am getting one Perchilan Carrier cruiser coming into my heavily fortified sytem. Then that crusier never even launches it one squadron of figter/bombers (which maybe is another bug -needs looking into.)
