Tamaii, I've never seen such a responsive developer as you. Take your time with the 2017 puzzles. It is amazing that you've kept us happy with daily puzzles for four years now!! Thank you.
From Nuublarking on July 4th: open this url in your browser: http://chat.kongregate.com/gamez/0020/4650/live/dailyPuzzle.xml then click the refresh button. then load the game again, that should fix it. thanks to radag for posting this before
Again copied from radag (3rd April, 2015):
as I figured out the problem with the failing to download daily puzzle is caused by the cached file http://chat.kongregate.com/gamez/0020/4650/live/dailyPuzzle.xml which is not updated automatically. In firefox and Safari (maybe in other browsers too) you can just follow this link and press Ctrl+F5 (Cmd+R). This should solve the problem till the next month.
