Issue with the new 'completed' challenge classes on the PoE Website (0 defaults to 28)

As mentioned in title and is affecting some of my stuff i scrape.

Now seems you use 'challenges23' < e.g. challenges#number to display the icon/number of completed challenges on the guild page, and forums etc..

However I can't find what you do if they have 0 completed.
I've modified it to 'challenges', 'challenges0', 'challengesnone' etc and they all default the image to the '28' completed image.

Ah, seems for '0' or no display of icon you remove both the classes, and ther eis no challenges0 etc..
