Hey everyone. 
  
I have been playing halo 4 since it launched. I am currently level 70.  A little over a week ago I noticed that I am no longer receiving xp points at all. I have played multiplayer, war games every game that halo 4 has, and It does not add any points whether I lose the match or win.  I also noticed that for some apparent reason, I have 100% unsportsmanship which started about the same time. These are false reports, as I have always been a team player and never intentionally kill my teammates.  My question is, does anyone know why I am not receiving any xp points and could it have anything to do with unsportsmanship?  I talked to xbox, but they referred me to this website. Any help would be greatly appreciated. Thank You so much!
