I finished my Phaeton gunner commendation and at the and of the game i had retrieving data and now i have no packs to open in the open packs tab, what i have to do? Is gone forever?
Same thing happened to me today except with the Warden Slayer commendation (and the Forerunner Destroyer commendation consequently) and I had retrieving data at the end of the game, and I didn’t get my packs either, I think it just takes a while to register, a couple of weeks ago I got my last ground pound and the reward pack didn’t show up till a week later, give it some time, you’ll probably get it
Damn, I’ve almost finished the commendation (2 frags missings) so I hope I will not have this problem 
Have patience !
It will come, give it time.
Thanks everyone!
