I'm trying to get the Efficient Operative trophy on PS4 and it doesn't pop at all... I finished a random assignement in coop then solo, in Impossible 5+ both time with my crusader, and nothing.
I tried it again, with my techno adept. I asked a random assignement to the astropath Remigius Klemet, in impossible (+5 from my current level), did it from the begining to the reward screen, solo (with the help of my Kastelans of course), without using bonus items this time... And still nothing.
A friend is trying too with his assassin, and he can't get it either. Is that a bug or are we missing something ?
