Everytime I attack the relay, but end up killing the Hunters, I never get the Win Bonus and Match Bonus awards. Sometimes I kill the Hunters or destroy the relay (without being interrupted) and I still don’t get it. The same applies when I’m a Hunter. After a match, I don’t get the match bonus award. If I kill the Monster (or the clock runs out), I don’t get the Win Bonus award either. It happens most of the time I play.
That’s odd, I assume you are playing Hunt, is it perhaps possible your game isnt completely up to date? Also what is your platform?
I am on PS4. My game is always up to date. It happens in all game modes for me, solo and online.
