Make olc_save.c be loud if you can't save an area.
Code below should print to ch and let them know that they can't save a specific area if they're not a builder.
if ( !str_cmp( "world", arg1 ) )
{
save_area_list();
for( pArea = area_first; pArea; pArea = pArea->next )
{
/* Builder must be assigned this area. */
if ( !IS_BUILDER( ch, pArea ) )
continue;
save_area( pArea );
REMOVE_BIT( pArea->area_flags, AREA_CHANGED );
}
send_to_char( "You saved the world.\n\r", ch );
save_other_helps (NULL);
