I have noticed on a couple On Duty missions that once completed, I do not get the credit for it. This has also happened to a league member of mine too. Are there any solutions, or maybe I'm just missing something (i.e. level/CR cap)?
Can you be more specific? What instances? When you say not completed, you mean you are not loot locked? Are you talking about Journal missions that requires to complete On Duty instances? If it's this last scenario, you need to run the instances in the order mission gives to get credit
Yes, in the journal... I got the loot lockout, but did not get the credit in my mission journal. It told me to queue up for Area 51, did that and completed it, but I still have the journal mission.
