Now I experience another unsatisfactory consequence of this bug. Last night I accepted a friend request, but soon after it he went offline, and I went to sleep too. This morning I got a permanent green envelope, because while I was sleeping he wrote 2 chat messages, and then unfriended me. No I can't read those messages, and the envelope stays green. Forever?
This issue still persists.
Nothing extracted yet.
I get a notification about it with the green envelope (I like this new feature), but when the chat window is open for the friend that sent the message, it doesn't appear in the chat window. I have to close the tab, and reopen it.
