I can walk through any open door by turning left or right until the room behind the door appears though, and then clicking behind the door.
Or by using the free camera which however I personally find very confusing to operate.
I agree that the way clicking on the door opening closes the doors is irritating, and that often it’s a faff with the camera to get a view of the floor behind the door to click on. The grove entrance is always annoying, for example!
