Wtf? The thumbnail isn't the same as what I uploaded.

Anybody else seeing this image of Reimu with a parasol as this image's thumbnail?

Edit: From the above comment, I guess the answer is yes.

If that happens, what you need to do is to add the image to the Missing thumbnails pool. There's a job running automatically which regenerates thumbnails of the images in it.

Btw, the thumbnail of Reimu holding an umbrella is from post #793670.
