Just finished visiting my Starbase Tac level and noticed the NPC's when exiting the main room can't be bothered using the door. They seem to prefer walking thru the walls on either side. When they return to the room, they are halfway thru the door before it opens.
Perhaps they are Dividians in disguise? Spatial anomaly?
Also when one of them walks down the left hand ramp (as you enter the room) the NPC will partially enter the floor at the bottom of the ramp.
Of course this must be a new safety feature in case one slips and falls while walking. Will certainly prevent needless suffering. Good call devs!
