I have stopped receiving xp points after leveling up to level 49. Therefore, I am not able to level up. Have call xbox and they tried to be helpful but referred me this website. I would like to know what has happened. Xbox informed me that they have received calls relating to this topic and said it may have something to do with the double xp you get with mountain dew. I would just like someone to let me know how to fix it or to actually talk to a representative of 343 industries about this problems. Thanks
