I can't seem to get any Lost Artifact Fragments through my Archaeology missions. I've been repeatedly doing the other missions that yield other Grade 1 materials in order to clear them out and hopefully have a mission that yields Grade 1 Artifact Fragments, with no luck. Torhead claims "Memoirs of a Crimelord" gives them, but I've never seen that mission come up.
Is there something I'm missing here? Any other way to get them (besides the GTN if someone sells some)?
