The enigma protocol was a 1945 power activity but after the update from last week it got bugged into a 2005 activity with the enemies all being at 2020 power. This is a basic seasonal activity and it is currently being made even more of a challenge to play than even the expert version of the arena for the season. And thats when it manages to properly work even. There is also currently a bug with the timer as well so that it doesnt properly countdown as you are running through the mission untill eventually when it does start counting down the clock wont add anymore time as you hit the security nodes or kill timekeepers.
