Today i hit the xp cap online so i couldn't gain any higher ranks. I tought to myself that i would keep driving my friend around so he could get more kills. While this happened i got my last few wheelmans for the wheelman mastery commendation. When i whent into the commendation menue after the match i notived i hadnt progressed, but the count actually whent from 240/250 - 13/250 does anyone know what the f*** happened? cause i dont want to do all that over.
