Finally they showed up! Must have been a bug.

I just started crafting a couple weeks ago and it has been great but now I have moved up to grade 2 materials and everything else has missions such as grade 2 gemstones, grade 2 artifacts, but no grade 2 color crystal missions. I need grade 2 color crystals for a crystal I'm trying to craft in artifice. Do I need to advance my archaeology level further to unlock those missions? Any help will be very much appreciated and thank y
