Old filter stopped working recently about panflute HOT 2 CLOSED

Dear Sergio, thank you for your time.

It is completely my mistake, apparently I did not have koma-script installed in both machines. This is necessary for acro to work. My bad.

from panflute.

I haven't touched the code in the 5 months, so I'm guessing two options:

1. Something changed in Pandoc and you are using an updated version (which version of pandoc are you running?). I checked the changelog for pandoc-types and couldn't find anything that might lead to a problem.
2. Something changed in the input text which made a bug in the filter noticeable. But I'm reading the code and can't find any obvious problem.

I also tested it locally and it worked (on both pandoc 2.0 and 2.1.3):

C:\Git>pandoc --version
pandoc 2.1.3
Compiled with pandoc-types 1.17.4.2, texmath 0.10.1.1, skylighting 0.7.0.2
