Here's the issue:
Graal uses external servers for the images, so players constantly downloading files doesn't lag the server itself. For some reason(that no one can apparently fix) for Android and Flash users, they are always getting older versions of files.
The blue mask was uploaded originally, then was retroactively declined. However instead of adding the replacement mask as its own file they updated the file of the blue mask.
Because of the cache problem with Android and Flash, they're seeing the old file instead of the new mask that was uploaded in its place.
