I’ve first encountered this problem when developing my bot for Wikimedia servers on Discord. huggle-rc.wmflabs.org service continues to report edits, log actions and categorisation changes, but new pages don’t get reported. This continued in my testing for the last week or so and when I tested XmlRcs with Huggle.

As we’ve checked with @Iluvatar, XmlRcs is silent about any new pages in ruwiki, even when API method still reports them. I’ve not checked whether the issue persists in other wikis.

Github issue in my library (with relevant code):
