There are a few permanent apartments available throughout Bigworld's towns and cities,
being available to every player; but there are also regions and towns, that only have a couple
of “unique” flats and chambers available, meaning: first comes, first takes.
These “unique” estates can add a bit of excitement to the game, when the number of users
is fixed and below - let's say a dozen.
But on world wide reachable servers, with hiscore lists being completely filled
and new players need to reach level 32 and more to be listed in the TOP-1000, these “unique” apartments
are too few !

What is the secret, that a player has an ' _path_apartment ' file inside the var/crossfire/players/<player name>
directory, and other files inside 'apartment' directories of other cites in the maps package do not show up there ?

The answer is confusing, but it is the unique attribute of the EXIT archetype leading to the apartment map file.

Whenever the EXIT has the unique attribute set to 1 , then the player is getting an “unique” file ( copy )
of the map, the exit leads to, inside the var/crossfire/players/<player name> directory of the server .

Whenever this unique field is missing or set to 0 ( zero ), inside the arch-attributes-end block
of an exit type of a map file, the map is not copied into the player's status directory on the server and stays “globally unique” .

Cities that have only a fixed amount of apartments available are Stoneville and CityDeClouds .
There the player on the Metalforge server will as of today only be able to drop large amounts of gems
to be swallowed into the nirvana just for a gate to open and no generator implemented to give something for the sacrificed monetaries. ← BUG !

What to do ?
Implementing it at home @ localhost !

Stoneville has four permanent apartments available : house1, apartment2, apartment3, housebrxzl .
Stoneville's Adventurer's Guild has a few permanent chambers available, but offers only one key each chamber.

The four permanent apartments are accessible from the world map tile world/world_103_127 :

Brxzl's home has several stairs leading to other storeys on the same map file.
These stairs act as exits, and need to be set unique 1 too.
A workaround could be considered by making the slaying field relative path inside the new location as
slaying _dragonisland_housebrxzl , but this works when the map finally is copied into the player_name/ directory.
The map files stay in RAM for seconds and minutes, before they will be copied to the player's directory,
and until then, the stairs would complain being “closed” .

So, housebrxzl needs to be patched also :

The Keysale house in Stoneville offers a few keys for the Stoneville Apartments.
The Key's “nrof” is only '1' , and whenever the player looses the key,
on a reset random map for example, the key will be lost forever.

The Altars are not set unique, nor the floor, they stand upon;
meaning being available for droppings after next map reset.
But the Keys and the floor tiles below them have unique 1 set,
meaning, there will be no new keys after next map reset.
