Pandoc's conversion to docx is very poor. \textbf{} doesn't get converted for some reason — in fact, the entire line of text goes missing. Which is shit, because I need to use \textbf{\textcolor{red}{Text}} if I'm to properly convert my workflow to avoid using Word.
Also, images inserted with the floatingfigure environment are excluded entirely.
Of course, conversion to PDF is flawless.
Wonder if that says more about the docx format than pandoc itself.
