Oh deep joy! Ah well, thanks for the reply guys.

Today I reached level 50 and started a Specialization. Not long after reaching 51, I completed the monthly challenge to win 30 war games matches. I got 30k XP and went straight to level 54. I know this because I customized the visor of my new helmet which is unlocked at specialization level 4. I then turned my xbox off. Now when I have come back, I am only level 52 . I dont mind the 2 rank drop, its the waste of 30k XP I spent so long unlocking. It still says I have completed the challenge but I have no XP to show for it. What has happened there and what can I do?!
