What blows my mind even more is that I completed one of the seasonal challenges during that run and I still have that calling card unlocked, but the dark ops calling card got reset
@ATVIAssist I reached over round 100 in CoD zombies, my game finished, I unlocked the calling card, I check the leaderboards, my game crashes, and the calling card is now locked and my highest round is 54. I have photo proof of both reaching round 100 and dying on round 103.
@ATVIAssist I tried to contact Activision support through the website since this should be a fixable issue. Instead, I'm told that I have to REDO THE CHALLENGE because you can't "add/modify stats in-game." Here's the proof.
