var buffer = writer2.GetBytes();

Should change to:

using (var writer2 = new ByteWriter())
            {
                foreach (var packet in Packets)
                {
                    var data = packet.GetBytes();
                    if (data.Length > 0x1FFF)
                    {
                        throw new IOException("Packet too big!");
                    }
                    writer2.WriteUInt16((ushort)data.Length);
                    writer2.WriteBytes(data);
                }
                var buffer = writer2.GetBytes();
                if (buffer.Length > 0x1FFF)
                {
                    throw new IOException("Packet data too big!");
                }
                writer.WriteUInt16((ushort)(buffer.Length & 0x1FFF));
                writer.WriteBytes(buffer);
            }
