I have contacted Bungie and Microsoft about this issue and am unsure how to resolve it.
According to Bungie.net I have the achievmen "From Hell's Heart", but accourding to my Xbox and live it is still locked.
I have contacted Bungie, they told me that in order for it to be on bungie.net it first has to be authorized by Xbox Live, this means i have to unlock it first on my xbox to view it on my bungie accoun, so the fact that is on my bungie account means i unlocked it. Now i have contacted bungie and microsoft and i have an computer IT background as my job is computer networking ans security, i though this in so thay others know that i understand how the servers work because Bungie says it is a server error, this means data packets were lost, now Microsoft hasnt really heard about this kind off error from what i have been getting when i call support, although the issue has been escalated (don't completely understand the Microsoft term but i imagine that means something is going to happen).

Here is my Bungie Achievment list (must sign in to view): http://www.bungie.net/Stats/Reach/Achievements.aspx?player=spartan355597
As you can see from the achievment list link, I unlocked "From Hells Heart" on Sunday December 18, 2011.
Now i have been told that the servers are being worked on, but the servers being worked on today and the fact that i got it last year have nothing to do with each other.
So anyone have any idea on whats going on?
