I've asked on the developers list, and nobody knows a reason for this
anachronistic structure. Any time there are 2 different copies of the
same data, there's bound to be trouble keeping them synchronized.
The server side doesn't depend on its validity. It is refreshed just
before use in common/aicore/cm.c cm_query_result():
/* Refresh the city. Otherwise the CM can give wrong results or just be
* slower than necessary. Note that cities are often passed in in an
* unrefreshed state (which should probably be fixed). */
generic_city_refresh(pcity, TRUE);

There are a total of 37 references. Many of them (client and server)
could be replaced with a direct reference to the main map tiles!
Most of this code is devoted to updating it, and sanity checking it.
