Not that i know of, maybe you added more games of another console to your collection? Or otherwise it's just temp gone.

That's strange - I've never heard of emblems going AWOL. Even if they were discontinued, I don't see them being ripped off of profiles.

It is strictly based on your collection of Games. You have to have more than a certain amount of games and 50% or greater of one console to get that emblem. You must have changed your collection to sway that.

Yeah sometimes that happens once in awhile...
