i have the motion flex v2.0 for world at war and when i click 10th prestige level 65 and get a kill online it never works, ive done it on online zombies while being the host and ive tried it in the old school 10th lobby and the mod menu lobby then i retried it plus i hit up on the dpad before and after i selected my prestige and everytime i did all these prosesses i got a kill online and nothing happened, what do i do?
