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?
