Did they nerf the amount of Frozen Souls since Day 1? I played the mission a few times on both the first day and on Saturday and it seemed like there were barely any Frozen Souls outside of the boss room on the second day as opposed to being all over the god damn place initially. As far as I can tell, there are either way less of them in general throughout the mission, there are less when playing in a group, or I experienced some awful and horrible bug the first day.
Probably. If they didn't, they better do it.
