Do you mean Blackguards 2? I didn't get a flag for Blackguards.

I really hope that Blackguards (1) has now finally received all the updates it needs ;)
Regarding Blackguards 2 I did receive a flag but no changelog for now.

Yeah, I though the same thing. ;)
Welcome back Judas.

That shouldn't be the case. I submit Linux-made Zip files to Windows-using professors all the time.

What tool are you using? (I normally use zip -rTm whatever.zip whatever/ or 7z a whatever.zip whatever/)

Should work in theory. I've never had problems with Linux made zip files working on other platforms anyway. I always do it from the commandline with "zip" though rather than a GUI.

From MaGog's logs for 2 July:

NOTE! CHANGED FILE MDK, downloadables, making of MDK booklet (German) (mdk_making_of_german.zip ***TO*** mdk_making_of_deutsch.zip; Sun, 31 May 2015 13:28:03 GMT ***TO*** Thu, 02 Jul 2015 18:07:59 GMT; 18,189,572 ***TO*** 18,175,199)

NOTE! CHANGED MDK, changelog (http://www.an-ovel.com/downloads/chg/chg_6.htm)
NOTE! ADD +++ Changelog for 02.07.2015:
NOTE! ADD +++ We've fixed the seemingly corrupted archive for the German version of the "MDK - Making Of" booklet.

[A flag appeared, but no game was marked as "updated". A few minutes later, without any action on my part, the flag disappeared. I then manually instructed MaGog to check this game, based on Judas's post above.]

[GOG game page bug fix]





[Additionally, the corrupt formatting of the "Witcher Adventure Game" changelog has been fixed (and version dates have been added). Thank you, Judas, for all the fixes]

Off topic, but could you take a look into changing Lords of Xulima's release date? In the store page, it's mentioned as having been released on 15 January, but the game's official release date was 14 November 2014.

Thank you, Chamb.

That works just fine but you didn't make a .zip file, you made a .tar.gz. Different compression format.
