After upgrade to MediaWiki 1.22 on plwikisource new pages are not marked as "checked" on recent changes and their view/edit/history pages. It hits either all or at least most users that has administrator/editor rights. It can be fixed for a single revision by an empty edit, even made by a user without editor rights. After the empty edit, the initial page is always "checked" by its creator. Some caching problem? Similar effect appears earlier accidentally, but never persists for longer than few hours. Currently it persists for about 3 days.
