As background info: I was playing TEC and had max-supply sized fleet. Had about 30 squads of mixed fighters and bombers.
I don't know if it's a bug that only happens when there are too many ships fighting, but essentially my fightercraft would launch and then just sit there doing nothing. I would have to manually order them to target the enemy (and yes i checked their attack status it was still on auto-attack), and after they killed it they would stop and do nothing again.
Anybody run into this?
