Katiilein: I thought the 1.1 patch was already included in the gog version after its release together with the Troll DLC... I got the troll DLC... and I don't see the Patch 1.1 to download anywhere just the polish language versions
I don't think they've updated the download to include 1.1 quite yet. You were able to download Troll Trouble with 1.0, but you had to do it manually and it didn't work for a lot of people. If you didn't download it separately and it's not letting you update to 1.2 then I'd have to ask what it says when you try to install 1.2.
I'm including a picture to show you where the patch is, just in case you're still on 1.0 (you download it from the GOG site, not the launcher).
