Interestingly, when the client loses connection and cannot get it back it often just “pretends” to keep going but doesn’t allow you to actually do anything. You will still see shooting but get no damage updates etc. Often the client refuses to close until minutes later. I’ve found teh best way to solve that particular issue is to attempt a session change, like undocking, docking or jumping etc. This tends to poke the client into realizing it’s lost connection and giving you the socket closed box which allows you to close the client.
Couple of friends as well as me have experienced client issues last few days so I don’t think you’re alone.
