Thanks so much for playing!
I also encountered the "someone tell..." message when Jippity ran admin_shutdown, and I never figured out what causes it, but I figure it works out since the AI is being disconnected. That's good to know that I'm not giving an error message when `cd` has the wrong number of arguments.
Also, you're the maker of Tony! I only thought of making Jippity after seeing your project. I intended to test my game with Tony as well, but ran out of time.
