Loenas: I've retried. My command line is just:
"lgogdownloader --list-details --language=524287 --platform=7 "
and I don't get any DLC information for any game.
I only get sections installers, extras, and patches.
I did an account refresh, didn't change a thing.
I also tried pillars alone (instead of all games) and don't get a DLC section.
That's weird. I would have guessed that the issue was with Witcher 3.
It seems like GOG can't decide what the hell they want to do with Witcher 3 DLCs.
First the DLCs were listed in the JSON.
Then DLCs were removed and added as extras but the "dlcCount" information from JSON was 0.
Now the DLCs are once again moved to be listed as DLCs in the JSON but "dlcCount" information from JSON is still 0.
I added couple of options in
834e6ba to ignore DLC count information from account page to work around similar issue for Witcher 3 but it might also help in your case.
--ignore-dlc-count option sets regular expression for games to ignore DLC count
Game specific option "ignore-dlc-count" can be set in $XDG_CONFIG_HOME/lgogdownloader/gamename.conf
Example:
To ignore DLC count information for Witcher 3 you can use
--ignore-dlc-count the_witcher_3_wild_hunt
or create $XDG_CONFIG_HOME/lgogdownloader/the_witcher_3_wild_hunt.conf which contains
{
"ignore-dlc-count": true
}
