As far as I can tell, I haven't found it and I can't really zoom or unzoom in the area. First time there and I got a message in the corner to find it, and it's not there.
Welp.. I just went to Oppidan Avenue for the first time, got the message, and sure enough there was a Qurazy Quoin... Maybe they do want seam streets to get Qurazy Quoins?
