Livesplit crashed partway through, so I measured the time through my video editor. The time comes out to 1h18m35s49f. Not sure if I should round up or down.

One save made in the last level, although I did not use it. I think this somehow messed up the in-game timer after the mission.

I had a less-than ideal Mission 2, and I lost a transport ship to scourge in Mission 6, which was a surprise. I had to restart Mission 8 and Mission 9 once each, so lots of room to save time still. I think I could hit sub 1h15m, which is my goal for now.
