Quite often I have noticed that aliens are trying to shoot me through walls. It seems to happen quite often that they will shoot through the wall, then move around it to a place where they could have shot me if they had just moved first. Is the problem maybe that they are just getting the execution order of their turn mixed up? They intend to move then shoot, but they shoot then move instead? They never try and reaction fire through walls, only on their turn so I doubt it is a faulty LOS/LOF issue.
