Exterminate! Challenge not completing

I have done MULTIPLE games in which I have killed every member of the enemy team. Which playlists are not allowed for this challenge? I have only played swat today, if that is the issue.

I dont think it counts if people on the enemy team leave and new people join. I had to complete about 4 games to actually get it because people would leave near the end and i had to hurry and kill the new people that joined.

It’s not broken, it’s just that the way they put the requirements for an extermination, it requires you to kill everyone on the enemy team regardless if they quit or joined in late.

So there could have been a total of 10 enemies players, but only got 8 because 2 of the 10 quit at the start of the game before you could kill them (just an example)
