Challenges not tracking made me lose the only good camo ever released for this game.

This dog ass game wouldn't track the earn the most score quest even tho I did it like 7 times. So then I tried to do the one in warzone but I don't have that installed bc its also ass, so I started installing it only for it to re download THE ENTIRE 200 GB GAME. But then it finally installed with 30 min left in the event but when I load in the event is gone and I miss the camo I grinded hours for. Wtf
