Talkin' Science sounds like the holdup. IIRC, that's part of the Aurora plotline that eventually leads to the Eastern Wastes. I remember thinking that it was odd to have a mission requiring a building that seemed like an optional bonus before, but I built one when I had spare Skulls a long time ago, so it wasn't a problem for me.
