The Riven Twins standing still

my 1st bow playthrough and after the cutscene I instantly started shooting him from the spot cutscene leaves you at and he didn’t move at all just used his ranged attack few times but that’s all

I had a similar experience. No issue on my 1st and 2nd playthrough. But on my 3rd one, using a bow this time, on the new patch, about 75% of the fight was me standing still, shooting at him from afar with the bow, and him just waiting to get hit.

I had the same issue.

hmm interesting, thanks for the report.
