I reported this bug too - was able to bring up the bug report dialog box and file it - hopefully the screenshot of Zoe outside the little girl's room went with the report ok. Was also quite fascinating to walk a great distance away (couldn't get back into the room, anyway) - there is a double sphere enclosing that room.

Yeah you get that double sphere in the Dreamtime where you meet the Vagabond too, if you get Zoe far enough away from where he stands.
And also there is a glitch that made Zoe float/hover above that map (collisions still seemed to work along the edges of the cliff, but Zoe was high above the ground walking on air).
I reported both, but the second one I can't reproduce easily (though my report was very near to the spot where the glitch happened so, maybe the developers have enough clues to figure out why that happens).
