That specific automation bug I actually addressed in the latest 0.2.3 update... or so I thought? If you're playing on browser, your comment is valid regardless. If you downloaded and in the bottom right of the main menu still displays an earlier version (0.2.2 or 0.2.1), try redownloading with the new update. Please do let me know if its still an issue and an exact example would help so I can pin it down/recreate it.
