I'm using the Ultimate Edition 2.02
In the Dread Lords campaign, during the mission Escape, the mission is to take over a planet. When I invade, I notice that their tech bonus is negative 40ish and that my attack advantage is about -21000. I'm pretty sure this makes it impossible to win. I maxed all my techs related to soldiering and went in with 20,000 troops instead of the 1,000 that probably should have done the trick. I still couldn't kill any of their 20 guys.
I wonder if anyone else has noticed this or if everyone with the ultimate edition just stops on the earlier buggy campaign mission that makes you defeat all your allies with influence starbases to continue.
I'm surprised the game was released in this condition - I've heard such good things about it. Maybe most players don't care about the campaigns or something.
