FFn behaving erratically

[classicdrogn]

For the past several days, when I try to view a Favorite Stories page (any of them) sometimes it will behave normally, and sometimes the most recent updates it will show are from months ago, typically July, sometimes as far back as May. Has anyone else been seeing this, or am I just some middle-point cache's extra-special friend? Tossing my own browser cache has no effect.
