Server randomly shows different content when trying to look at this link

This link showed up on the front page as a post about the search for the secret cow level, posted to the diablo community, but clicking it sometimes shows a post about The Mets and sometimes it's a post about dating advice in the phillipines community.

Note that URL in screenshot is the same as the link I posted, and the right column shows correct community info.

Reloading the page replaced the content with the correct post about diablo.
