I hope this was only a bug... I am pretty sure anyway.

When I exited the game, I got a notice as I was exiting that I was logged in from another computer... As if someone was logging into my account and the game was ending my session. Hopefully nobody is trying to get into my account, but as I said, it was immediately after I exited the game so I am pretty sure it was just a bug.

Just to be on the safe side, I changed my password
