It's happening in Chrome on both my home and work machines. (Other browsers seem to be immune)

The "Complete thread" post list is omitting some posts. They show up on the main page, but not when viewing a single post. Any replies to the omitted post are also hidden.

I've cleared my cookies and cleared my cache, but neither seems to fix it.

It's annoying when you see a new post in the "latest posts" box, click on it, and then are unable to get any context (without opening every other post in thread-view)
