It appears that I have earned both versions of Where in the World?
The description states:

I accidentally assigned the images to the wrong hats, and three of us missed it in testing. I was not able to get to fix this until today, which happened to be a few hours after the hat became activated. So it ended up that some folks got hat with Id 21, which used to have the Moon image, and now has the sun image (and vice versa). Hat labels got corrected, but still had some caching places to clear out. Etc etc, this is the result.
sun and moon got kerfuffled
should be all good now
