If you are having problems with other players villages and parishes not showing on the map screen, this information should help you:
You can try locating and deleting the file/s “VillageData100.dat” (World 1) and/or "VillageData101.dat" (World 2) located in the following folders. The files/folders are hidden though, so you may want to turn them on/visible (operating system dependant where it'll be located) :
* C:\Documents and Settings\User\Application Data\Firefly Studios\Stronghold Kingdoms (** hidden folders need to be visible)
Windows Vista 32/64 / Windows 7 32/64
* C:\Users\[USERNAME]\AppData (hidden folder)\Roaming\Firefly Studios\Stronghold Kingdoms
Turn off the game then delete the file/s VillageData100.dat and/or VillageData101.dat then restart the game.
** If you open My Computer, click on Tools in the top menu open Folder Options and within the View tab you will see Hidden files and folders and Show hidden files and folders.
