Promo Code Conflict Bug, Is It Just Me?

I think I found a new bug that hasnt been reported yet.

I got 2 Promo Codes for Halo 4, one for buying Collector’s Edition (Which rocks btw) and one for pre-ordering via Amazon. my Amazon promo code ddint come in my email until today, when I put it in I appear to have lost my unlocked Emblems and Prime Armor from being a Collector’s Edition owner.

I had input the codes for being a collector yesterday when I first started playing the game after work and had Prime armor until I went to sleep that night. When I woke up today I redeemed my Amazon Promo code then fired up Halo 4 to find that I couldnt find any WEB armor skins or my Prime Emblems or Armor.

Anyone else experience anything similar? I had gone into customize and when I realized I had lost my Prime stuffs I turned the xbox off without letting it save my changes. I was quite attached to the Eagle Prime Emblem…

A quick update in case anyone else suffers the same bug:

I went into my Hard Drive Storage, found Halo 4, Halo 4 Game Unlock Data and made a copy to the Storage Unit. I then went into the storage unit and copied it back to it’s spot in the Hard Drive. This brought back not only my prime armor mods and emblem sets but also the Web Armor that was missing. Seems to be holding for now after 2 restarts!
