Issue is that player is dropped, and server is receiving this message, heartbeat from client but server doesn't know about client as it has already been dropped.15528.483 Info ServerRouter.cpp:242: Received message type(ClientToServerHeartbeat) heartbeat(sequenceNumber(222695785) ) requestsForHeartbeats() from unknown address(redact), so the peer id can't be deduced.
Save file and logs are available on request, since I haven't sanitised it.
Server is being run on Ubuntu 16.04, dual Xeon L5420 and 8GB of RAM, in a datacenter in California
