Can someone explain to me how this ranking works? I played for like 20 minutes earlier, nearly got to rank 1 and turned it off. Most of my kills were with the sniper. I turn it on now, everything is reset. I thought okay, I'll play a while, sniped again. Got 5 or so sniper kills in a match there and check my stats, no sniper kills, no shots fired, no time with the weapon at all. I had unlocked the sensor earlier but now I haven't, wtf?
