I managed to find this post from CDPR:
Welcome to CD PROJEKT RED Technical Support! Here you will find help regarding our games and services, as well as answers to frequently asked questions.

So it looks like a bug (apparently affecting only someone) after all. Let's hope it will be solved quickly.
The other thing to mention though is, that is quite sad to see, how CDPR still (don't) communicate with the communitiy just the next day after Burza and Slama literally apologized for the bad communication and admitted it had been a mistake. And the outcome? No reaction on FB, no reaction here. Have anyone from the developer's team ever heard of PR?
