Agatha Christie/Talk

you can force links to work by making any substantial change to the page the link appears on; you don't have to change spaces in the link to underscores. In fact, I avoid changing them to underscores because then the term you do that to doesn't show up in a search. You could instead copyedit or change some minor bit of punctuation; or even add an   somewhere in the article. That's html for a space, but the wikiware thinks the change is substantial enough that it quits accessing the cached version without the active links.
