Not sure if this is exclusive to the Terrans/Korath, but I played 3 games tonight with the Krynn/Krynn/Yor, and every game that I played against Terrans (with random opponents) they didnt build a single ship with a weapon. The Korath had the same problem in my final game as Yor. They were easily at the point of which a militarily oriented race like the Korath should be at least in their second tier of weapon techs, minimally. These were all on normal difficulty, and the Arceans and Torians built up respectable fleets in the games i played. Something is seriously wrong with the Terran/Korath AI under certain circumstances, at least. They kept building small hulled ships with no attack or defense over their planets, labeled as "Defenders", but obviously they did nothing.
I really hope this is fixed soon, because i hate not being able to select random for races. Thx guys, love the game and expect some growing pains in beta.
