MedeaFleecestealer: Just had Zantai post this over on the GD forum.
"Quick update for GOG users:
Unfortunately as of this morning, v1.1.7.1 is still not working on GOG. It appears to be a GOG Galaxy issue.
The build is on the servers, if you uninstall the game and just do a fresh instal of v1.1.7.1, it will work. However, if you have v1.1.7.0 installed and try to update to v1.1.7.1, the installation will fail to copy/move/instal a GOG .dll file.
GOG is able to repro it and they are working on a solution, but until they resolve it, the only workaround for GOG users is a clean full installation. Don’t think forcing every GOG user to reinstall is a good solution, so hopefully they will have something for us soon.
We’ll update you guys when this is resolved. Sorry for the inconvenience."
Just tried it, but new install just gives me 1.1.7.0 again.
