I cannot finish the "Patrol the Z-6 Sector", as subtitle mission "Patrol Fvillhail system" allows me to complete all the objectives except "depart system". The screen comes up that I can depart the system, as the mission is complete...but the sidebar on the right does not give me a check mark for departing system..and then the transition to "hail starfleet".
1) Make sure you're not in combat. I've noticed a few times after I kill the last ship in a patrol that if I exit while in combat it won't complete.
2) Make sure it was the correct mission...seems like sometimes when I join an instance team it gives me the mission for that zone, but won't check it off in my quest log, though I'll still get a mission complete message and credits/merits, just no completion on my log.
