I know this was mentioned on the previous page by TemmieOfficial, but I have something to add.
I leave the 1.5.60 beta open and I don't know if it is a result of temporary connection issues or VPN or anything, but i notice the avatar and my name goes away and when it does, I can't click on "unowned freebies".
I suspect when the connection drops, there isn't a way to re-connect without closing and re-opening the Client.
Maybe this could be resolved with a "reconnect" button."
Unfortunately, I just realized that if I click "logout" it crashes with a Java thing of 2 problems. I assumed it was the same error screen as closing from the task bar, but it is different. I will see if I can get that and attach it as a file.
It also appears, at least for "freebies", that it doesn't update when the avatar isn't working.
Update, i disconnected long enough for it to disconnect and reconnected, but that didn't do it. I don't want to leave my internet off for a few minutes to test, but since it isn't an instant thing, it means it might be a time-out issue, meaning after you connect, it stays connected for a maximum length of time, then logs out automatically.
