what does that mean?

I just posted chapter of a story at AO3, but instead of 14 chapters, it says there are 13. The new addition shows on the chapter index of the fic though. Is anyone else having trouble posting things? It took me forever to get that sucker up there, too. I'm exhausted from cursing and typing. Curtyping. Typursing. It's been an exhausting *week*, ya'll.
