The first Blight you encounter in Rymrgard's Realm in the Animancy tower doesn't trigger combat, attacking it is similiar to attacking a totem/ward out of combat.
Entering the first floor from the Second floor of the Port Maje Tavern causes a glitch where you are unable to walk through the tavern itself, save for a small area near the stairs.
Similiar Pathing issues in the Engwithian digsite after the fight with the Drake & Panthers where Xoti and Player character were unable to walk through the Center circle of the Digsite. Xoti ended out clipping through the Ramp/Staircase leadin
