This problem seems to align with the timing of the last patch.

I am using Steam client and Java is current (build 1.7.0_06-b24).
I have a solid internet connection with minimal network traffic so there is nothing eating bandwidth.

I can be anywhere in the clockworks (D14 last instance), I get some in game lag, no in game indication of poor connectivity and then will sporadically disconnect.

I can immediately reconnect but do not return to my previous location.
Instead, I find myself back in the intro lobby.
Previously - even with a full router crash / power outage, I could always return provided I didn't timeout in the game client.

Needless to say - this is becoming frustrating.

Any suggestions / fixes / ideas appreciated.
