i need to contact 343 to get the 17343 experience applied to my account because i beat the 117 challenge and after it added the exp to my account the next game it took it away but it says the challenge is completed. any info would help as to how i can get this resolved. and no i havent hit the exp cap for today, ive only played a few matches and it did not give me the message stating i hit my cap for matchmaking exp.
