Listen up, Android users. If you're using Google Now, don't go to its Settings -> My Stuff and try to modify sports teams or stocks right now, as doing so completely borks the whole app. As soon as you go back to the main screen or click into Search, you will experience a force close. Repeated attempts to restart it will result in a crash as well:
The only thing that works is clearing out Google Search's data in Settings -> Applications, after which you need to re-enroll into Google Now. Changing your Home or Work locations does not seem to trigger the issue - it's just sports teams and stocks.
