Okay, so I've just noticed that you can cause a disconnect from the server by destroying vines randomly. It wasn't possible before to destroy hanging vines before, so something might have changed about that very recently. Now I can do that, and once I do, I get disconnected with 10 second delay or so. Reconnected, twice, did it again... then this.
Also, this appeared later in the message log:
