Have a look at the history of [[Pim Fortuyn]]

http://www.wikipedia.com/wiki/Pim_Fortuyn&action=history

All versions are properly listed and stored correctly as far as I can tell. However, starting with the version of Tuesday May 7, 8:59, the diffs are screwed up. They do not compare to the next version, but to very old versions.

I noticed that on the Talk page, Tim Shell explained one of his edits to the main article early Tuesday morning, and I remember seeing that edit (taking out the label "right wing"). This change however does not show up on the main page's history page.

Does anybody have an idea what is going on here? Are similar things happening on other pages?
