AnakngAraw provided us with proof that statistics motivate. She is one of our hardest workers and localises for a Tagalog public. Her complaint was that the daily updates of statistics did not happen any more.
Keeping our community happy is really important for us and even though Siebrand is really busy making a difference at the Wikimedia Chapter conference in Berlin, he found the time to look into it.
One of the affected statistics is the "group statistics", it show what percentage of defined groups are localised in a language for MediaWiki. Statistics like this are generated by a pywikipedia bot and the software was broken. With a quick hack it is fixed locally and our numbers are up to date again.
