I have some bugs to report as well, some same as OP:
Battle viewer - sound will occasionally cut off and stay off requiring a reload of the game to return battle viewer sounds, and occasionally you get a CTD when attempting to reload.
Battle Viewer - Action too close... need to allow some use of the mouse wheel to pull the camera back... especially in battles with star bases or shipyards. either mouse wheel control or pull back the camera in top down or cinematic views.
Drone ability - I get a CTD when AI attacks a shipyard when I have the race ability "paranoid" to have drones and I want to go to battle viewer... I can resolve the fight automatically but I get CTD every time I want to use battle viewer.
Battle Viewer - I also see ships start with red damage icons even when they are undamaged.
I have opt-in patch installed, FYI.
