Achievements Won't Unlock For Me

Just wondering if there is a way to fix this?

I have 3 Castle DLC achievements that won’t unlock. I’ve read online a bit and it appears many people have different ones that just refuse to unlock despite doing them multiple times.

What are the steps to right this? Is it anything I can do or do I have to wait for a Halo 4 title update? Its some of the first achievements I’ve ever NOT been able to earn. It’s really frustrating.

The 3 that won’t unlock are:

Hello Nurse
Ashes to Ashes

My gamertag is Blu Willis if that helps.
I know I’m not alone on this, just curious if anyone is even working on solving this or if I should just give up on this matter. I’ll continue to play, it’s just a bit of a bummer…

Sadly, this is a common issue. Here’s the official thread to post about it. You might be interested in this list of reported achievements and this theory as to what is going wrong.
