Hi jamesob. Thanks for the heads up about the extra border in Crystal Caves. I fixed it and promoted a new version, but it will only affect new games, not games in progress already. Also, fyi - your review is listed as 'unrated'. I think this is due to a bug in the board ratings that Tom is working on. Check out this thread for details:
