Just reached level 100 yesterday and now It won't let me level up any higher. Its not letting me pick any other specializations or earn any XP.. It shows me 6 specializations including Spartan-IV and I have them all completed. I just need pioneer, rogue, and engineer to complete but their not showing up. I have been playing matchmaking and its not giving me any of the XP because it has me stuck. Has anyone had this problem?? Do I need a code to pass this. Someone Help me out please!!!!
