I completed the mission over 24 hours ago and am still not receiving the mission from Mazka. All I am getting is Calhoun's Hostile Engagements and the Exploration.
I hate the Hostile Engagements because the PvP system is bad and takes WAY to long to get into just one competition since the queue is obscenely long. Also, half the time I get invited to one, no opponents except one show up.
Yesterday, I was able to get all three missions: Chart, PvP, and Into the Fray.
