Current Event Weirdness

On Tue 8th July I logged into my account and had a weird kill replay thing after my first game. I also had the challenges for the current event "Future Icons". However, after the first game I got a server error ad the Kill Replay vanished along with the Future Icons challenges. I didn't think anything of it until I just played a game of Team Deathmatch where in-game the Future Icons Challenges show but in the challenges tab after the game ended they're no longer there.

Is the event still active? And if so, how do I get my challenges for it  back?
