The Flight North hiding places...

Where do I have to go to see how many I found? Wiki says to go into the ruins and wait a few seconds, and it'll display a message, but I've been back several times, going back as far as the first brazier, and haven't seen a message. Do I have to go back to the first room? I currently have no idea if I have found any of them, so I'd like to not have to do the mission again. I did search the forums, multiple times, but found nothing.

......ruins as in ruined houses, it displays when you discover them

I went to all of those, following the map on Wiki, and never saw any message. Thats what I had originaly thought was supposed to happen, but when it didnt happen, I checked the wiki, and saw that it said to stand in the ruins a bit, I thought that meant the tunnels.
