A few minor issues still remain, and they should be getting fixes soon.
Although almost everything at this point has now been addressed, The Witcher 3 still suffers from a few minor issues on all platforms. While none of it is anything major, they do stack up and become annoying over a period of time.
Thankfully, it seems as though a lot of these problems will be getting fixes pretty soon- CD Projekt RED community manager Marcin Momot has confirmed that new hotfixes for the consoles and PC versions of the game will be coming soon. These hotfixes, reports GeekSnack, will address the Steam achievements issues, as well as the Skellige Most Wanted Quest issue that prevents some from completing the quest.
So basically, if you are a completionist, or if you had run into any of these problems that had impeded your progress through the game, you are now going to be in luck- these issues will be resolved soon.
The Witcher 3: Wild Hunt is available now on PS4, Xbox One, and PC.
