I had the same problem as plsdontbug. I had the double Xp in lobby. I was first one in game. But none of the featuers worked except disable killcam. Now I did this without invites. i just went solo. Joined an excisting game and then after first round had double xp in lobby but not in game. played about 7 rounds and one did not show double xp symbol in lobby and nothing changed in game. So it seems realy good so far. Just need to get the double xp part repaired.
