I ran into this a few days ago. The pictures will describe everything.
I select this image on the favorites page.
This is what I get. The four samples are completely different due to the fact that the structure & style references are missing. There is about 85 images stored on the favorites page, they are all affected, except the 15 recent ones.
The reason I have 85 is due to the other bug where I can't delete anything on the favorites page. The unfavorite method doesn't work and I posted that in the thread concerning that issue.
Any help would be greatly appreciated to recover these images.
