Yes, I just finished it.
And I didn't encounter any major bugs, or quests breaking bugs actually.
From critics and comments, I was expecting far worse in that area.
Sometimes there are occasional graphic glitchs, a floating fruit in Talanzaar or a flying cart in a riss field, nothing exiting and reloading can't fix if it turn into a bother.
Only moment of worrying I had was during the Darosham's rescue in the main quest, if the cutscene don't execute well and you face invisible or standing still foes afterwards, just exit without saving, then reload from before the cut scene and it should solve the issue. It did for me.
Hm, and to be complete, the Twon ha riding is, not the most convenient in some places like Okriana little streets and backalley, you will prefer to walk after a while.
So, I don't know if it's the hotfix or if I were lucky, but the 'all the bugs' reputation from this remaster seem undeserved to me.
