NO MAP CHALLENGES IF YOU CAN'T GUARANTEE I CAN PLAY THE MAP!!!

I’m just 20 kills away from completing the challenge for firefight at Outpost and the damn map never comes up in the available maps! I’m getting pissed off and tired!

When doing Score Attack or Firefight matchmaking, select none of the above to get a different map selection. It can take a couple of rounds of voting but Outpost does come up.
