I've been running through the grind. I like it, but I've never finished bo2 levelling before. I don't see a reason to disable unlock all like the others said.
That being said, would be nice if all of the challenges tracked properly.. found a few that don't track at all.
Been playing a bunch lately trying to see how far I can get on challenge completion.
I've noticed 3 that don't track properly, so far.
Kills while your UAV is up.
Combat record shows almost 1k UAV uses. I always have it equipped, but the 100 kill challenge won't complete. (I swear I am getting kills lol)
Deathmachine kills (and uses)
Deathmachine kills are stuck at 0, whether using deathmachine from a cp or getting the killstreak. Also the combat record shows uses at 0 as well. Despite having earned the killstreak several times.
War Machine kills (and uses)
Same as death machine above.
I do have a legit Steam copy. Every other challenge appears to be working properly.
I have tried on a few different servers with the same results.
Thanks!
