Network - Client still in Network.Connections after disconnect

Hello,

When my clients disconnect (using Network.Disconnet()), my server gets this callback:

     void OnPlayerDisconnected(NetworkPlayer player)
     {
         Network.RemoveRPCs(player);
         PlayerStats.Remove(player);
         LoopConnections();
     } 

In my LoopConnections(), I loop over all connections

     string Score = "";
     
     foreach (NetworkPlayer player in Network.connections)
     {
         Score += PlayerStats[player].Name + " " + PlayerStats[player].Points + System.Environment.NewLine;
     }

(Playerstats is a dictionary)

For some reason the player that just disconnected is still in the Network.connections array, which gives me a Dictionary-access error (since I removed the entry before loopconnections()). Why is the NetworkPlayer still present?
