In the main comments I mentioned a CTD, here are the details: Vision of the Future campaign, Imperials faction, attacking the planet Birgis with no lead ship (meaning all ships leaving hyperspace at the same time at the beginning of the battle), with a fleet containing the Megador, a few Imperial-class and Victory-class Star Destroyers as well as mixed smaller escorts. As soon as the battle began, the camera showed a close up of a unit, the screen froze, then CTD. It's happened only once, has not repeated. Hope this helps.
