[Plugin: Vote It Up] Post has disappeared from top 10 widget

Hi all,

Today I checked the top-ten widget for newest votes and the #2 post has disappeared from the list. The plugin has been working flawless until today. I haven’t modified the post at all, it’s still active and published on the site. When I visit the post it properly displays the # of votes but is not in the sidebar.

The website (NSFW) is https://holyhangover.com/

and the post in question is
https://holyhangover.com/2009/06/09/actressmodel-los-angeles-ca-286

Any ideas on what would make a post suddenly disappear from the top votes widget? Thanks!
