I logged in today, and saw i needed to complete 4 games of matchmaking for the daily challenge. The same number of games i needed to win to be the monthly challenge. I went into infinity Slayer and won four games which put me from lvl 48 to 49. I equipped the arms it unlocks and then logged off. I logged back in and played a game. When the game was over i was 48 again as if i had not played at all today. I still have the bracers equipped that unlock at 49. 343 Please restore me the missing exp. You can see the games in my game history its 4 games inf infinity slayer today 11/20 followed by a game of oddball. I will be taking a screenshot of me w/ the lvl 49 armor at lvl 48 and adding it to my fileshare. The EXP loss is well over 10 games worth.
