First of all, the game set my language to Polish by default and as befits a magnificently lazy person, I failed to change it to English, so I'll be guessing most of quest names, titles, et cetera.
So, when you meet Eder, you get the quest to bring him along when you'll be chatting with Maerwald the Wacko. I complied, he even delivered the final blow when our little chat got somewhat out of hand, but according to my journal, I'm still supposed to bring Eder to Maerwald. I think it's clear now that decapitation of the Wacko may slightly complicate things for me.
Is this a bug or I shouldn't worry and everything's gonna be ok a little later? If the kind soul that delivers me the answer could do it without including any spoilers, I would be twoplus grateful.
Btw, since I'm already here, does anyone know how the GOG version is going to update itself? There are some minor bugs that are likely to be fixed soon and since all other GOG games I own haven't seen a patch in a decade or so, I was wondering. There's no "check for updates" button in the game itself either.
