While traversing the western side of the Northwest Airfield I was cornered by zombies in one of the single room barrack buildings. While fighting back with a combat knife and mosin I backed up between rows bunk beds. I was knocked unconscious and woke up having clipped inside the corner of a bunk bed unable to move or turn and died to blood loss after being knocked unconscious again.
Similar corpse or unconscious body clipping issues seemed to occur semi-regularly during my play, often making zombie corpses unlootable as they get stuck in walls.
