--- Comment #16 from Bob Igo bob@igo.name 2012-06-05 22:11:36 CDT --- I have experienced that the game plays normally until lag/framerate issues occur. After that point, chat messages cease to work (definitely outgoing, possibly incoming), and the aforementioned error message is inevitable, as is the buggy post-error behavior of the game client. I can also confirm that it started happening June 4th.
