I am following a path through a chain of doors through about 3 or 4 more rooms, killing stuff (mainly with Egyptian Magic's Call the Sandstorm, supplemented with other spells as needed). The game locks up completely (doesn't crash to desktop, just freezes) when I get to the small room filled primarily with Big Reds. It's happened twice so far and figured it probably wasn't a coincidence. This last time, all I was doing was moving away from the room which was filled with the Sandstorm and a couple of living walls. I also had a charmed heckraven (I'm not sure how much of this is relevant). I am not using any mods. I've attached my autosave file.
