Now on sale tab is broken now.
See screenshot.
Left is Firefox, Right is Google Chrome.

GOG just announced the 2.5 days Special Sale, but the Sale is still showed as Weekly Sale on "Now on sale" tab.
It is misleading.

Featured deals tab on homepage show a lot of zero discount games.

Only selected browsers are welcomed to our store website. That's ONE strange way to sell more games ;)

is anyone else seeing (on firefox) a "game overlay" card in their games library? the game count checks out with my backup. my reciepts seem to point to witcher 3 free dlc program.

You're not the only one https://www.gog.com/forum/general/strange_game_on_my_shelf/page1

As tiredliger said, you're not the only one. I had it too. Just do an account refresh.

On a side note, doing an account refresh also removes the "New" tag; thanks GOG, I appreciate one more bug.

Yeah well, GOG thinks that everything's peachy regarding this particular one. It's quite likely that they think the same about other issues.

I noticed a bad trend in the already stellar collection of GOG failings piling up. It happen that new installers are often wrong on both website and galaxy. The usual form is that you see the installer divided in parts on website when they are indeed different installer with wrong name (it could be two different version numbero or either 32 and 64bit version). On galaxy it could happen that a single link will download both of them (for instance both 32 and 64 bit) or that it fail to download altogether. It's becoming really frustrating making a backup of your own purchases.

The "Works On:" section has disappeared from the game pages of numerous (but not all) games. This seems primarily to affect games added to GOG in the last couple of months. These were still present until two days ago, at least for the games that MaGog is monitoring. Here are some examples:
- Descent (2019)
- Galactic Civilizations III - Star Control Heroes [DLC]
- Jill of the Jungle: The Complete Trilogy
- Project Highrise: Architect's Edition [Premium]
- Shadows: Awakening - Legendary Armory Pack [DLC]
- Shadows: Awakening - The Chromaton Chronicles [DLC]
- This War of Mine: Stories - The Last Broadcast [DLC]
- Tyranny - Gold Edition [Premium]

Last night I hit the USD-only bug, and a trip to the checkout page fixed it; but shortly afterwards I hit another bug with prices of items in the shopping cart being calcuated incorrectly (instead of items totalling £16.XX I was suddenly seeing items totalling £19.XX). It fixed itself on a page load.

Bug #1
GOG rename the Black Friday Sale to Cyber Monday, make a big new banner for it, but the URL it linked still showed as Black Friday Sale.
Everybody knew that was On Sale tab, GOG just renamed it to Black Friday Sale.
GOG staff are just too lazy and not capable to make a more appealing Sale page.

Bug #2
FLASHBACK is not showed on New tab of homepage.

Is anyone else getting two entries for the Party Hard 2 forum (see attached screenshot)?

They have different url addresses (first one:https://www.gog.com/forum/party_hard_2#1542147635, second one: https://www.gog.com/forum/party_hard_2#-62169991200), but they both resolve to the same forum content.
