My password keeps clearing from v6 client rather than remaining saved, the only thing I can think of that might possibly have caused this was a change in my IP address while I was using a VPN connection and opened the client.
I'm not sure ~why~ the client would feel the need to clear out my password whenever my IP address changes? It gets really frustrating and I just wind up not logging on at all rather than have to go to my inbox and dig out the password once again.
