Broken challenge?

For some reason it seems that the Regicide challenge for 6100XP is broken. I’ve managed to get 18 in a few matches (NOT an easy thing to do). For some reason even though the challenge is for in a single match, it says I’m stuck at 10 Regicides still and it won’t change. This is also happening to a friend of mine, so it’s not just me.

Some kinda bug. Hopefully 343 can address this because it’s lame.

Bump. Also have received this bug. Anyone else? I haven’t seen anything posted about the Issue Being Investigated in said thread.

Yep. This is really frustrating…

I could’ve sworn that I completed this challenge yesterday (though I definitely never got 18 regicides in one match), but I got back on today and it was at 0/18 incomplete. So I played some more regicide, and mine was also staying at 10/18. I dunno what’s going on.
