So I have 4/5 clues but when I go to the Aethon System, there is no story mission there for me to complete.  Not sure how to progress now and I was wondering if anybody had any advice or a way to fix this.  Forgot to mention this is the part where I have to travel to three possible locations to find the Magos Biologis.  I have been to two of the areas but the third is gone.  I played the mission helping a friend but it didn't alter my storyline at all.
