Acronym properties may have changed. Rerun to get them(acro) synchronized. about acro HOT 5 OPEN

Are you sure there are no other errors or warnings in the log file? The rerun warning is often benign and (if not vanishing on multiple compilations) more likely to be another symptom of whatever is preventing the list from updating.

from acro.

1. Usage of package `parskip' together(scrbook) with a KOMA-Script class is not recommended.
2. Usage of package `fancyhdr' together(scrbook) with a KOMA-Script class is not recommended.
3. Acronym properties may have changed. Rerun to get them(acro) synchronized.

So that's all I get, but I suppose that it shouldn't have to do anything with the KOMA-Script conflict.

I could also add the whole log, but I don't know if that will be very helpful.

Yeah, warnings look fine. I see you're using subfiles, how are you loading the ./setup/packages.tex and ./setup/acronyms.tex files? Is the \printacronyms call in thesis.tex or a different file? Presumably all \ac uses occur in a \subfile-loaded file?

from acro.

The following contains the structure of the thesis.tex. All \ac uses occur in the subfiles of mainmatter

\input{setup/packages.tex}
\input{setup/acronyms.tex}

\begin{document}
\frontmatter
	\input{setup/titlepage.tex}
        \input{setup/declaration.tex}
        \input{setup/dedication.tex}

        \subfile{Abstract.tex}

        \tableofcontents
        \listoffigures
        \listoftables
	\printacronyms[name = {List of Acronyms}]

Hmm, everything looks to be behaving, I wondered whether something might be generated in one .aux file and the list reading from another, but with this configuration everything looks ok.

\begin{filecontents}{setup/acronyms.tex}
\DeclareAcronym{foo}{short=foo,long=foo,}
\DeclareAcronym{bar}{short=bar,long=bar,}
\end{filecontents}

\begin{filecontents}{Text.tex}
\documentclass[acro_iss249]{subfiles}
\begin{document}
Text \ac{foo}
\end{document}
\end{filecontents}


\documentclass{scrbook}
\usepackage{acro}
\usepackage{subfiles}

\input{setup/acronyms.tex}

\begin{document}
\printacronyms
\subfile{Text}
\end{document}

Presumably thesis.aux is successfully being written to on compilation of thesis.tex? Not otherwise sure what might be causing issues. Have you tried compiling with acro 3.8 (https://github.com/cgnieder/acro/blob/9a56e414b0eb82ff89241decc66da9620f2292df/code/acro.sty)? Can you share what you get for grep \ACRO thesis.aux?
