Dishonored 2. 90% of the way done with Mission 8, the Duke's castle. I take my sweet time, putting all dudes to sleep. Just killing the level. Finally get to the Duke, go to put him in a sleeper hold on the outside steps, and he glitches INTO THE ####### steps. I can see his Icon, walk over it, stand on it, hell...he has called two Veterans to his glitch hold in the stairs, they can throw #### through the stairs at me, but I can't get to him. No way no how. Dark View shows them "inside" the steps, I've tried sleep darts, guns, etc...nothing can hit them, but they can hit me.
So 4 hours invested on this level, I think I need to start from scratch.
