Areas we had the effect:
~ 2nd Floor NE Air Tower standing in doorway between desk and cabinet.
~ 3rd Floor Industry Buildings (construction in cherno and NE ).
~ Roof of Hospitals (tested electro, cherno, and berenzino) all had same effect when standing in corners on upper roof platform.
As mentioned above, this may be in conjunction with the rubber banding issues, but it was instant. No movement, no free look with ALT, just random instant death. We went back a few times when spawned near those death areas, and found our bodies meters away from the building with all items ruined as if we fell.
