I got interested in what is going on. I had fully updated wallet, 32 connections to network and this is what was sent to me from a source that just started downloading the blockchain from startheight ~22000 (i did not write it down, doesnt matter). Same time about 64 blocks was orphaned and later found as PoS. This happend a week ago. Using Wireshark to analyze, decoding packet data to "bitcoin". At the time there was multiple IP's resyncing whole blockchain, keeping peers occupied I guess.
Decoded using "Bitcoin" option in Wireshark.
