Medal Glitch

I was playing 1v1 Octagon with a friend and I got a killtrocity. The killtrocity medal showed up in-game and when I watched it again in theatre, but in the postgame carnage report and on Halo Waypoint it did not show up. It’s not a big deal, I just don’t understand why it didn’t give me the medal.

Did you check in custom game medals? Just wondering why do you care about custom game medals?

That’s where I looked and I said it doesn’t really matter. If it happened to me in custom games imagine if it happened to somebody in say the MLG playlist.
