You have "Root page" with the content "[[/Subpage]]". And you have "Root page/Subpage" with any content. If you move "Root page" to a different title (e.g., "Beet page") and select the "move with subpages option", MediaWiki will move all of the pages as expected. However, when you open "Beet page" (the new root page title after the successful page move), you'll see a red link where [[/Subpage]] is. This indicates that the page has been re-parsed after the page move, but some time in between the root page being moved and the subpage(s) being moved. This behavior is wrong. The order should be tweaked so that the page text is re-parsed after all of the subpages have been moved, I think, if possible. The workaround is to manually purge the page (using ?action=purge or equivalent).
