I have completed 13 of 16 weekly PVP challenges but my ‘People Vs People’ (complete weekly PVP challenges) is at 8/10. What gives? 500k xp is a lot. It done the same to me last week too.
The three Halo 4 challenges (Repeat Survivor, Can’t Catch Me, and Just a Scratch) do NOT count towards “People vs Peoples”. Never have.
As for the other two, likely glitched, restarting the game you’ll find either People vs People shows 10/10 or some of your PvP challenges that looked complete will now show as almost finished.
This has happened to me twice before, but it was my fault. I finished the challenges but quit before the count
