I began having crashes to desktop at one point during my first playthrough, but those appear to be all to do with the physics engine; Happens every time I try to carry stuff around, which is really killing me at the moment, since I got into my head to bring the gnome with me this second time around; Try to carry him, and the game crashes, put him down and turn your back on him for a split second, and he will have disappeared, as will any stuff you may have been hoarding in one container or other (probably having had a physics engine intersection "explosion", against the collider of the bucket, and ended up outside of-, or stuck in- map geometry. :7
Man... Looking at how great the parallax mapping on bullet hole decals look, does nothing to relieve my regret that the walls do not have have it. :/
