I just noticed that the two new sales on GOG:

(https://www.gog.com/forum/general/special_offer_4_new_games_and_frogwares_publisher_sale_4e635)
(https://www.gog.com/forum/general/weekend_sale_bdetective_mystery_games_up_to_80_offb_d0754)

aren't advertised on the German main page of the shop.

I noticed this in the past already, so it's not the first time.
But this time is (afaIk) the first time, that it still hasn't been changed seven hours after a sale started.
