I dont use a mod :3 but I get the equivilent of no too far by following this method (If you have RTB there is a server pref manager which in effect does the same thing).
Go to your Blockland folder, go to Config, Server, then open up prefs.cs in something like Notepad.
(My file path in vista is C:\Blockland\config\server, yours may be C:\Program Files\Blockland\config\server)
Find the line in there which is
$Pref::Server::TooFarDistance = "60";
Then just change that to some inordinate number like
$Pref::Server::TooFarDistance = "999999999999999999999999999";
Save the file, restart blockland, should have worked.
