Why do you need so specify any master server if you want to run a server that is not advertised?!

<syntaxhighlight lang="cpp">
class MasterServerLauncher extends Info; //[3369] Issue #1

function BeginPlay()
{
local MasterServerUplink M;
local int i;

for(i = 0; i < class'MasterServerLink'.default.MasterServerList.Length; i++)
{
Log("Creating master server uplink for" @ class'MasterServerLink'.default.MasterServerList[i].Address $ ":" $ class'MasterServerLink'.default.MasterServerList[i].Port, 'MasterServerLauncher');
M = Spawn(class'MasterServerUplink');
M.myMasterServer = i;
//This must only be called on one master server link
if (i == 0)
M.UplinkAndStats();
M.Reconnect();

if (! class'MasterServerUplink'.default.DoUplink) break;
}

Destroy();
}
</syntaxhighlight>

The <code>MasterServerUplink</code> object isn't solely for reporting information to a master server. It has multiple functions:

# '''Establishing network play'''
# Starting up the link to GameSpy, if <code>UplinkToGamespy</code> is requested in addition to <code>DoUplink</code>
# Starting up the link to GameStats if <code>SendStats</code> is requested in addition to <code>DoUplink</code>
# Starting up the link to a master server, if <code>DoUplink</code> is requested

The reason one of these objects is always required is for activity '''1''', even if things '''2''', '''3''' and '''4''' are configured off.

In the code above there is a call to <code>M.UplinkAndStats();</code> which performs steps '''1''' to '''3''' from the list above. Here it is (cut down) so you can follow the logic:

<syntaxhighlight lang="cpp">
function UplinkAndStats()
{
local class<UdpLink> LinkClass;

NetworkConnect(); // this is my point 1 above

if( DoUplink )
{
if( UplinkToGamespy )
{
// set up link to gamespy
}

if( SendStats )
{
// set up link to stats server
}
}
}
</syntaxhighlight>

The next line after <code>M.UplinkAndStats();</code> in the code you quoted is a call to the C++ engine code:

<code>M.Reconnect();</code>

Within that engine function there is a check on <code>DoUplink</code>. If it is set to true, it starts up a master server link. If not, it does not establish that link and instead outputs this line in the log:

<blockquote>
MasterServerUplink: DoUplink is False, not connecting to master server(s)
</blockquote>
