During the most recent Winter Dreams Event, my friends list glitched and said 2 of my friends were in a room. Everytime I tried to go to the same room the friends list just popped away and nothing happened. After the event was over, I relogged to see if it fixed everything, and they were GONE! None of us removed each other! @cait and @MagicIshaan can back me up on this. @Lily says it's happening to her as well.
