The "Last Post" Column Of The "Recent Forum Activity" Section Of The Main Page Is Around 6 to 8 Hours Out Of Date

When viewing http://www.giantbomb.com/ the section at the bottom of the page detailing recent forum activity does not display the correct entries for the last posts made in the topics shown. Many of the threads listed contain posts that are significantly newer than the "Last Post" shown. The problem persists after refresh and is present in both the signed-in and not signed-in views.

Consider the following two images captured a few seconds apart:

For all if the threads shown none list any last posts newer than about 6 hours.

Given the nature of this but it is also unclear as to whether the proper topics are being surfaced. If I had to guess as to a cause I would wager it's either bad caching or a dead task.

@paulwgraham: Can confirm, the topics listed there are different from those listed at giantbomb.com/forums and also super old. Nice catch.
