The height of the hostage rooms and the width of the doorways leading into them should be within ~4u of the original based on the new player model dimensions
not sure if they changed the player model from what it was in 1.6?
if your talking about the pic with the laundary room then its because I took the picture up in the corner on top of a shelf
there isn't any frames around the doors/windows either so the door my look large then it really is in those screenshots(64x96)
