On Friday, I had no trouble starting Internet games against the AI. (Connecting to other people's games was problematic, but there's other threads about that). Then, starting on Saturday, I haven't been able to start a game against the AI. I set up the game, click "ready", click "launch game" and then I get the standard Light vs Dark screen with the Tip at the bottom. At this point nothing happens (It stays on this screen for ever ... I've let it run for hours just to see) ... the Tip doesn't even change.

The last line in my log file is:

"info: Sim::Create() crashed: attempt to get as string a nil value
      stack traceback:"

Is there any way to submit a complete log file to the developers to provide them with as much information as possible about the problem?
