Hey engineers, there's an issue with the wiki: whenever you edit a page, the thumbnail information vanishes from the search engine. Instead, you just get the standard "no pic" image, regardless of whether or not there's actually a default image on that page.
Images have a weird habit of breaking and then coming back too. I don't know if it's related, but I saw it happen a few times while editing blogs/lists.
I'm on the latest Chrome and Win 7 versions.
