disconnect event has no peer data

[winsvega]

Apparently when using

while (enet_host_service(m_server, &event, 0) > 0)
{
        switch (event.type)
        {
              case ENET_EVENT_TYPE_DISCONNECT:
        }
}
``

an event comes with peer data removed. 
so event.peer->data   is 0
event.peer->connectionID is 0
all is nulled and I have no way to tell who has disconnected.

the workaround is to store a map of peer pointers in memory itself represented as int or str.
