I've been playing this game for about 27 hours and I'm really enjoying it.
But I've come to realize that every time an achievement is unlocked that it is not registering to my xbox live account.

Is there anything I need to know about?

Here's a link to show how long I've played and the percentage completed. Even though I'm 90% through the game.
