ok, so i commented here about an year ago, and my enghlish was verry bad.
There is a bug/ghlitch, where you can trap the house owner in a closet, and she won't get out, because, if you try to open the doors(to trap her you need to close the doors), the AI will close them back, and will not try to exit.
How did u get there ?.. And yeah it is empty, but it has sound and smoke :)
