Hm, Miyu, maybe you saved before the latest patch? Though I do know EllaCharmed mentioned that each time she enters CAW to make more changes the tears are bigger than they were before. So, if you are like me and save after every big step... it might be there will be more corruption faster than if you could make all the changes at once and save that file just once. Something to think about.
I took more pictures of the uneven edges that are much clearer than before, so maybe every time I save the edges get worse. Or maybe I just know what I am looking for now. Any way, I took pics of what you want to block with rocks and shrubs, but Photobucket has put all the photos in a bucket now!
