What's going on here? Some kind of MediaWiki caching problem?
I tried to upload a darker version, but it still showed the bright one as current. So I uploaded it again, and now the previously uploaded version appeared dark, but the newly uploaded one bright. So I reverted to the previously uploaded version (which shows as dark in the File history), but still, it shows the bright image as current. What's happening here?
