While looting residential (tenement_building_small) buildings in Novodmitrovsk I could not find any items in them. I 'poked' my head through building's texture outside on a ground level and saw quite a few small 1x1/2x1 items available on a first floor alone. The problem was reaching them since the were hovering just about 5-10 centimeters bellow the floor's texture, and therefore, were unseen and unreachable. Small Note: Huge items like Crispy flackes or Cooking pot that are (2x2 or more in the inventory) were seen as half wedged in the floor and at times reachable, but all smaller items(knifes, tools, axes, pills, shirts/pants) 2x1 were still unreachable.
