		<td>
@ref page_type_66
		</td><td>    This flag defines the destined map as "personal unique map". If set,
    there will be a separate version of that map for every player out there.
    This feature is used for the permanent apartments
    (in Scorn/Nuernberg/Caterham...). It should not be used for anything else
    than apartments, since Crossfire is a *multi*player game. In such a permanent
    apartment don't forget to set the unique-flag for all floor tiles too
    (see floors).
    An exit pointing outside of a personal unique map must have the
    "unique destination"-flag unset.</td>

		<td>
@ref page_type_211, @ref page_type_67, @ref page_type_88
		</td><td>    Unique floor means that any items dropped on that spot
    will be saved beyond map reset. For permanent apartments,
    all floor tiles must be set &lt;unique map&gt;.</td>

		<td>
@ref page_type_21
		</td><td>    Unique items exist only one time on a server. If the item

    This can be used if you want to sell apartments on your
    map: Simply sell a unique passport/key, and place
    an inventory checker at the entrance of your apartment.</td>
