Well... if I left the refugee sector through the door that leads back to the landing pad, the Red Eclipse showed up right away. If I left using the airspeeder, though, they would never show up, and I couldn't advance any further. It seemed to be the direct cause of them not showing up, at least in that game.

One thing that seems to cause this: if you use the airspeeder to travel around Nar Shaddaa before the Red Eclipse shows up, it cancels the cutscene and they don't. I tested this in my most recent game, and it was definitely the cause.
