I chose to extract from a Defense Mission and it went to the mission complete fade out but did not remove me from the squad, leaving me stuck like this in perma-slow-motion which made it very hard to even move or aim or do much of anything but killing enemies that got near me looked amazing. They exploded in slow motion all Matrix-like. At the next rotation, I was able to extract with my team but not leave squad. I had to exit the game.
