Well that's promising!
Fingers crossed, although I would say that the standard blue may just be a default if there is a failure to load the custom image, or if the database drops out or something to keep a consistent experience.
In saying that, this sort of stuff does happen when they are performing upgrades and they have an outage on one of their systems that is not highly available.
On another note....I can't update my profile picture. Is this some sort of upgrade once I've been in the game for so long or something?
