[Sanctuary onslaught rewards missing PS4]

I just did a match of sanctuary onslaught with a friend with the intent of farming khora's blueprint, however after zone 2 my UI froze so for the rest of the match i had no information of the match progress. Once we finished zone 8 my friend told me we had gotten khora's blueprint, however no reward showed up for me and the mission summary also had no rewards... 

I've done this mission all the way to zone 8 too many times and now that I should have finally gotten the reward the game just glitched out...
