Sometimes when I view "Today's Posts/New Posts"

Threads will show up as having a new post within, But when I try to view said thread I don't see any new post.

Most recent example, tonight I have posted on two different threads. Both show up as having a new post after mine. But my post is the most recent one I am able to view.

It doesn't matter time of day, if I view as Guest, or if I'm logged in. Or viewing on full site or mobile version.

This has happened to me A few times now within the last two weeks.
