Ending mission camera and script

At the end of mission 9 of the main campaign, as I just killed 17/19 enemies of the last wave, the camera stucks and pans as if the mission is finished. But actually the end mission scripts don't trigger and the game continues - except I can't really play since the camera is stuck. There's also a message about one of my blade lotus being destroyed that keeps being displayed on screen.

I saved the game at this point, reloaded it, and the scripts (Mentor's voice, transition wipe and so on) triggered immediately, signifying the end of the mission.
