Has anyone else had this issue??? its doing my head in!!! ive been stuck on games won 21 and the same amount of kills/deaths/assisits for 3-4 games probably longer i even got the 20 win achivment before the ''stats'' said i had reached 20.... ive also had a 18/0 KD using a mantis and the ''perfection'' comendation did not update, or is this commendation not applicable to vehicles? Im no hardcore Halo player, only just getting back into the series but i like to compare my stats to other people and ive come to not trust anything stats or commendations say anymore.., come on 343.... this is simple stuff you should be getting right!!!
