My friends list group: General, has been moving down in terms of alphabetical order.
Since the groups are ordered based on alphabetic, General should be higher than, per say: good ranked.
However, even though I move the group up manually to its originally position in patch 4.20, ever since 4.21, the "general" group will always move down upon relogging.
This is what it looks like upon relogging: http://i.imgur.com/ReoeXzb.jpg
It's extremely frustrating because I have to manually move the group every time I log in.
