I can not get backfilling working after the player disconnects and tries to return to the same server. Matchmaker allocates a new server. I assume the reason is that the PlayerId submitted to the matchmaker is the same, so the matchmaker can't assign it to the server where it was previously registered. So I need to call UpdateBackfillTicket from the server with that playerID removed. But I can't figure out how to associate the connected player with the PlayerID that he submitted to the matchmaker. I'm not using the Netcode package so I am receiving only connectionID of the player when he connects. Do I need that player to send his multiplay services playerID so I can later remove it from the list?
