There’s this weird bug (or a feature!) with Drifting shade affix in NmD, sometimes it triggers, sometimes not, I believe if it hits you on its edge and not in a center you get this complete darkness that lingers even after you leave the area of effect. Normally if you stay inside of it you can still see your character but cannot use abilities etc, but when bugged even your character disappears, total darkness and can use abilities, this lasts for good 3 second before clearing out, do you guys have any similar experience with this?
same happening to me today, clipping the edge of the Nightmare field gave me a black screen effect that lingered up to 2 full screens away from the puddle, multiple times.
Drifting shade disappeared several times in the NM dungeon for more than a minute before respawning.
Just all around buggy behavior through the NM dungeon with the affect.
