 If you want to have live updating markers and player-markers on all maps, turn on the `write-markers-interval` and the 
 `write-players-interval` in each `plugin.conf` on the other servers.  
 **Or** if you plan on hosting the entire map with an external-webserver you can reverse-proxy each maps live-interface to the correct
