I've installed a new piece of code into the file database today that manually checks file pages for broken areas. Many people have found mod pages that are only half complete, often missing the right hand side of the page. If you come across a file page with this problem you can click the "Page Broken?" link next to the file name and the system will first check to make sure the page is broken (to stop abuse of the caching system) then reload the cached page if a problem is found.
Hopefully this provides a fix to this annoying problem for normal members of the site.
