This is the packet it is saying is a problem

void ProtocolGame::sendMapDescription(const Position& pos)
{
    NetworkMessage msg;
    msg.addByte(0x64);
    msg.addPosition(player->getPosition());
    GetMapDescription(pos.x - Map::maxClientViewportX, pos.y - Map::maxClientViewportY, pos.z, (Map::maxClientViewportX * 2) + 2, (Map::maxClientViewportY * 2) + 2, msg);
    writeToOutputBuffer(msg);
}
