I created an arranged team and invited PiE.
The chat box then said that Guinsoo had joined the game.
But the picture at the top with the avatar said "PiE".
Guinsoo than began to chat (it was guinsoo after all).
Then it said "Guinsoo has left the game"
And when he left, the picture + avatar at the top of "PiE" left simultaneously.

was very strange.

I've had similar issues with users that had their name changed.

This same thing happen with a game I played this past weekend. At first I thought I was crazy, but then I read this post.

Definitely will keep an eye-out for this one, this weekend.
