Many have noticed including myself that the avatars aren't working correctly. When I was uploading a new photo to change my avatar it didn't work ( even though the image is good enough to change). And also I've noticed that some avatars go back to the default icon.

Is there any real cause to why this happened? minus there's some reports saying there's a hacker.
