THERE ARE BARELY ANY BUGS FOR THIS GAME!!! GOOD JOB STARDOCK PEOPLE, AND SORRY YOU HAVE TO DEAL WITH SO MANY WHINY PEOPLE. FOR ALL YOU HATERS GO PLAY CIVILIZATION 4, AND IF YOU LIKE THE GAME KEEP PLAYING IT!!!
Sorry your highness. Should we not discuss the game and it's features in your presence?
If you have never noticed the defense bug that is not because it is not there, simply that you are not playing the game at a) a high enough difficulty or

you do not pay enough attention to the battles and ships in your game.
That being said, fine, you play the game at a level fit for you, but don't preach about what is and is not there just because you lack the depth of game play to come across it.
If the defense bug was not affecting game play do you really think the devs would have spent time on it?
The list of changes has been posted, it is in another thread.
Dammit, where is Wheel? He usually takes care of this ignorance.
