Unmissing friends

I about a week ago cut loose 4 friends, reluctantly of course. Their avatars still appear, even though my count is down. One ex-friend  seems to be perpetually logged in, as does another friend who has not been unfriended.

Are these two separate bugs, glitches or anomalies, or are they intertwined?

Do I need to file two different requests?

Fixed fast. Well done!

Thank you so much for all your support, Harry!

Only too pleased to support good old chess.cam and Garry thanks you too, however belatedly, and all the other pawn want to say thank you, too. 

Politeness pays.
