I played through Spartan Ops on Legendary the first week and the challenge for that never showed up as completed.
The current Drilled challenge to get 18 kills with a precision loadout weapon in a single match shows as completed even though my service record says the most kills I’ve ever gotten in a single game is 17.
When a challenge is completed, why aren’t its XP added to the rest at the end of the game so we can see we’ve really gotten credit for them?
I’m having a similar problem with the current weekly challenge “Deadeye”. I went into a “Capture the flag” game with 12 head shot kills already counted towards the challenge total of 70, I got 15 head shot kills during the game (I know this as I was awarded 15 head shot medals) but the challenge still reads that I only have 12 head shot kills, I understand that it may take some time to refresh the total challenge kills but it’s been almost an hour.
Yeah, my buddy and I were both stuck on 12 headshots for the Deadeye challenge. To add to these issues, I have completed 25 challenges, yet no achievement popped. Also, the other day I was nearly finished a challenge when the Halo server went down in the middle of the day. When it came back up, my challenge had been reset to 0. I’m hoping they fix these issues pretty soon.
