When cropping a picture for thumbnail and feed, the crop wont stay. The thumbnail resets to a general cut of the image once you refresh, or load any other page.
I have the same issue. I got it to work on two pics, i'm not sure how it works.
Just wanted to point out this is still an issue. It'd be nice to be able to choose how the thumbnail is cropped if we're stuck with square thumbnails.
The site has undergone some updates, and from what I can see, this issue has been fixed; cropped images should now stay the way they were cropped. If you have any continuing issues with this, feel free to comment here.
