Hello @phezzan.
Yes, I was say what that fixed, but I was wrong!. This trouble do not fixed.
On dedic where my server is hosted I have a few IP address. I run server with ip some_target_ip but in wireshark I saw what I connect to another IP. I try test that, mb a few ip is reason of bug, but I don't sure.
I also play with my friend. He from another country but he do not have that trouble / bug.
Also, when I leave, my "player" a few time do not exit from server and when I try reconnect I can't. Server think what I already on server.
I was kick "me" from server and then I can connect to the server.
Sometimes that bug is disapear, sometimes that bug work from connect, sometimes from another "triggers". In currently (I was create new galaxy) that bug begin when I try "load" my ship from saved ships, then game is "broke" and I can't build anymore, send msg in chat etc.
