Not sure this is a bug; and as far as I can tell, doesn't break anything or cause any specific trouble. But in a conversation started last week, my Status remains the same on all subsequent posts, despite having updated it. Further, I just checked, and any threads I posted in before the change a) still has my old status message, and b) any new messages still show my old status message. This post will be a test to see if maybe my new status simply isn't showing up at all--but I think that the problem is that my old status message carries through on any in-progress threads or conversations. It's just not the behavior I would expect. If I change my Status message, I would expect any new posts to carry that new status.
