@eternal_sorrow: The --vcmi, --wog and --download options were removed by Ivan in this commit. They were responsible for download and install wog (wog.zip) and vcmi data files (core.zip which contains graphics for new resolutions). Now wog you can install through vcmilauncher (mod manager). As for the installation of core.zip here is the solution. I presume that in the future it will also be available to download through mod manager.
