Same issue here on the ps4. Currently doing the assault mastery and stuck on "Kill 7 enemies with explosives in a round" challenge. Been stuck on it for a while now so thought I'd not help my team and just fully focus on that challenge. So for the last two games of conquest I used panzerfaust, grenade launcher and grenades exclusively - both times I got 12 explosive kills by the end of the round but it only tracked one for the mastery challenge. It kept resetting the challenge mid-game because at one point it said I had 5/7 but on the next explosive kill it reset to 1/7! This is how controllers get broken...
Just happened on Xbox One. Working on Tides of War when all goals simply reset. It’s giving me credit for playing the rounds but zero lightening strikes goals/chapter rewards. Last Tides, I had completed all assignments and issued nothing in rewards. Makes me not want to continue playing this game type.
