I did the breifings to get this head (FOS1: chasm and FOS2: Power core) and got each individual reward, but I never got the banished kryptonian head peice style which is the reward for completing both breifings.
There is a bug currently affecting the larger Collections Briefings and Investigations. It's being looked into. I would put in a ticket tho instead of waiting for a fix.
I think I saw in another thread that the master briefings, investigations, and collections currently have issues on live. No quote from a Dev, but one of the players in the thread below says they talked to support, its a known issue, but they don't know when it will be fixed. https://forums.daybreakgames.com/dc...fing-sets-are-not-sending-bonus-items.294684/
I do not have the master collection, and I know that and posted this after I tried that and even relieved a few times.
