I don't know how else to put it. It's just horribly immersion breaking that I can be sitting inside a huge open door in a room full of windows without glass and the building is surrounded by gas but somehow it never comes inside....
Gas is already easy enough to ignore, if you brought a mask, but the fact that it COMPLETELY ignores building interiors regardless of how many holes there are in the walls or ceiling really just takes it from "passable" to "nearly useless".
