No , you're not, it's like this since the "new" shelves, DLC are in the Mac OSX section if you select this page..... they never bothered to fix the issue (they'll fix this when they have the time, from what they told me -> meaning never, since the downloader is no more "supported")

Wait, so these are the actual Windows installers and not Mac versions at all?

Well, there isn't a Mac version for Witcher 3 yet.

Correct, for the DLC "only" btw The Witcher 3 isn't avaible on MAC OSX according the gamecard

ah , ninjaed by our greek cat :)

and if there're any dlc avaible for MAC OSX it's correctly diplayed in the MAC OSX section , but the windows 's ones are borked.

Oh ye gods, I completely overlooked that. Ugh, GOG, get your crap in gear.

So this puzzle is solved now. GOG will only have to list these at the correct place and everybody will be happy :)

[It appears that the changelogs for versions 1.03, 1.04 and part of 1.05 have gone missing (or so at least it appears to MaGog --- as I do not own the game, can someone who does please check?). Could there be a 64KB size limit on the changelog?]

Yep, seems to be true. When I scroll down the last one I can see is 1.05

My guess is that GOG has a 64KB size limit on the changelog.

I'll wait and see whether they fix it. If not, I will modify MaGog to remember the lost portions, for I do not wish it to suffer from GOG's limitations.

[Apparently GOG chose to restore the lost changelog portions of version 1.0.5, but not the changelogs of versions 1.0.3 and 1.0.4. I guess MaGog will have to do that.]

Maybe Judas is still working on it? Have not seen him here stating his usual "fixed" yet.

At least you are the one telling us that someone actually still IS working on this issue which is also good to know :)
