Anyone else notice how all of the achievement  lists are missing the    Status Update: single achievement?

Isn't that a Master Challenge and not an actual achievement?

I don't think so its listed under achievements in the game but I could be wrong

It's a "Master Challenge" and not an actual achievement. They needed some form of standardized accomplishments without going over 200 gamerscore, so they made Master Challenges.

that's kinda silly why not just cut some points off something else and add it to that
