Im on my last sniper rifle I have to "get 100 1 shot kills" to go to the next camo, which is only the "choco" camo. Im stuck on 61 1shot kills, and won't go any further no matter how many 1shot kills I get. I tried everything. Even ran around with it as a primary weapon with no attachments. Stays on 61 no matter how many 1shotkills I get. What you think ????????
