Question

Hello

------------------------------------------------------
This way I solved the problem that the client crash the issue is this can bring some problem to the server? is it 100% safe?
------------------------------------------------------

open PythonNetworkStream.cpp
search :

bool CPythonNetworkStream::RecvErrorPacket(int header)
{
    TraceError("Phase %s does not handle this header (header: %d, last: %d, %d)",
        m_strPhase.c_str(), header, g_iLastPacket[0], g_iLastPacket[1]);

    ClearRecvBuffer();
    return true;
}

replace:

bool CPythonNetworkStream::RecvErrorPacket(int header)
{
    if (0 == header)
        return true;
}

new search: 

    if (!s_packetHeaderMap.Get(header, &PacketType))
    {
        TraceError("Unknown packet header: %d, last: %d %d", header, g_iLastPacket[0], g_iLastPacket[1]);
        ClearRecvBuffer();

        PostQuitMessage(0);
        return false;
    }

replace:

    if (!s_packetHeaderMap.Get(header, &PacketType))
    {
        if (0 == header)
            return true;
    }

No, its not safe nor good solution for unknown header packets.. Your client will not be closed if you receive wrong packets, but your whole client will go nuts (you will see that your level is 98865556, you will see nonsense items in your inventory etc.)

If you are getting "Unknown packet header : [random number], last: 251 250" then you can try to disable IMPROVED_PACKET_ENCRYPTION - but you will have to make some changes about buffer

unknown header errors are caused by the removal of missing or faulty codes from the server and client. To solve this problem, it is necessary to find out exactly where the error originates. this takes a lot of effort and time, it would be better for you if you develop untouched files in the mainline.
