On 3 separate occasions in halo 4, I have downloaded an update and my level drops. The first time, it completely dropped me to square one, as did the second time. The third time brought me from level 21 to level 16, which is huge for someone without xbox
live gold to help boost the amount of xp gained (a stupid concept for halo to make, but whatever). So, how can I fix this issue (and get my levels back without taking the hard route)?
