I was just looking at my crucible playlists for my Xbox Live account and noticed Timekeeper was shaded out. I knew I played a classic 6v6 match on Timekeeper and looked it up on my hunter. It was a clash match that I played on 9/26 @ 02:08 PST. You can check my crucible history and find it (keep laughter to a minimum, though).
I played this in my Xbox 360.
Anyway, just wanted to make you aware that there seems to be an issue granting a Grimoire card for this map.
