When using fncychap and hyperref together, the page number for references to the appendices are off. The Appendix A reference links to the first chapter, appendix B links to the second chapter, etc...
\documentclass{report}
\usepackage[]{hyperref}
\usepackage{fncychap}
\begin{document}
\pagestyle{plain}
\tableofcontents
\chapter{One} \label{one}
This refers to the page for chapter 1: \autoref{appendix}.
The table of contents is also off.
\appendix
\chapter{Two} \label{appendix}
This is the appendix
\end{document}
This creates a document where the references in the table of contents link appendix A to the wrong page number (page 2 instead of page 3).
