Has anyone been able to complete this quest with the 1.07 patch installed.

Close to the end of the quest I am unable to kill the Witch Hunters. It shows that I am hitting them for 0 points of damage. First Skellige's Most Wanted and now this quest.

Yes, just played that quest last night and was able to complete it with 1.07 installed. My other bugged quest was also Skellige's Most Wanted, but supposedly there was a fix from CDPR. Haven't gone back to try it yet though. (I may be too far into the end game now anyway.)

I have heard of people reinstalling 1.07, for other problems/bugs.

Yeah the quest seems to be bugged, though I managed to complete it with 1.0.7. But when I finished the main story the "reason of state" quest was reported as failed for some reason. I still got the correct epilogue scenes which correctly reflected the choices I made during the quest.

I was finally able to complete the quest. Hard to load a previoius saved file. Thanks for the replies.

Still have not been able to finish Skellige's Most Wanted yet.
