Changelog for patch GOG-3 (Windows) (added 23rd November 2015):

- Achievements are now unlockable for Legends of Eisenwald

No, they aren't! At least not in my game. Or at least not all of them...
I've started a new game and played the Prologue - that should have unlocked "Dog's Stash" and "Knowledge is power", but it did not.
I've also reloaded an old save and killed St. Landary, no "Colossus with feet of clay " either.
Did anyone manage to unlock achievements? Is there a special condition - like difficulty setting - to unlock them?
Or are they still broken?

Are achievements only available if you play through the Galaxy client?

I don't know. I haven't played the game yey. I just copy GOG's changelogs to the game forums for everybody to see them.

OK, thanks.

When will GOG have the last patch? There was one in end December 2015, and in January a dev said that some other patches had to arrive (with 2 DLCs).

Yeay!
What really annnoy me are not really bugs:
. Information is missing about the quests, we can't remember what we really have to do and how to choose the better.
. There should be more automatic pauses, so we don't miss some timed quests (we have to wait so we put the time to run very fast, but the pnj is runing under our nose and we miss it)
Those 2 are what made me stop playing (the 2nd made me quit after I was some lost).

Since Blood of November is a standalone expansion, I thought it would be better to have its own sticky Changelog. I've already made a new thread, so please use that thread to post the BoN changelogs. ;)

Works for me. :-)
