The game usually gets pretty exciting, but eventually I hit a dreaded point where the movement updates stop coming, but the client is still responsive (I can move and zoom, but no units are moving anymore). Then about 20 seconds later, the game disconnects saying the server has disconnected. I can't really seem to find anything common between the times that this has happened (3 so far, but basically every single large-ish AI game i've played). It's usually when I'm about to escalate my attacks on a stronghold. Anyone else experiencing this since 61450?
Not since 61450, but way earlier on the 5xxxx builds. It was my crappy router throwing a tantrum due to the large volume of traffic it had to handle. Can you still load website when this occurs? The symptoms you describe sound very much like you have lost your internet connection, or at least the connection to the server.
