The backdoor L-Point mission

I keep getting this weird bug: About the time I've shot down all the hostile ships, my cockpit vanishes from the view. Also I can't steer my craft anymore. If I hit esc, the pause screen comes up, but no menu buttons are visible. I once got through the mission without this bug, but the game crashed as I jumped back to Mwari.
Any ideas what I should do? Just skip the mission completely? I've got Version F14.6 with Jackson's Yard patch.
