Hey Barg,
Thanks for letting us know... I've checked what we can do about it... There is a setting in the settingsfile of openttd which is:
adjacent_stations = true
I've looked it up on the internet where it says:
Holding the Ctrl key while building a station directly adjacent to another one will create new station instead of merging the new tile(s) with the existing station.
Possible Settings: On or Off In Openttd.cfg config file:
([station] adjacent_stations = <true|false>)
Well, right now its on true on our servers, so maybe we have to change this to false! Then it will not be possible anymore to use the CTRL key in the game to create stations far away... But to do this I need to shut down the servers!
I will check when I can do this... I think tomorrow

Will start with server1 for the test
Thanks for letting us know
Regards,
Frank
