When I get the chance I'd like to add a full AAR, but for now just a quick and rather vague bug report. My tank having been knocked out in the explosion-kills-all-occupants manner, I exited. To my puzzlement, I found the same campaign still resumable when I booted up AC later in the day. Hitting C to continue, I was greeted with the names of the now deceased crew who were each being given a purple-heart (with the "posthumously" tag, of course). Then, despite commander replacement being set to realistic, I received, well, a replacement commander.
Edit: Just to add that my replacement commander proceeded to receive the Distinguished Service Cross for "extraordinary heroism" despite not yet having engaged in combat. Lucky guy!
Edit 2: Later, a message displayed spontaneously halfway through an encounter awarding me 2 VP for capturing a zone, despite enemy units still being in the vicinity. Subsequent encounters are terminating randomly and early, with VP awarded before I've destroyed all enemy units. These are not things I've encountered before, so this particular campaign might be in some way corrupted.
