Bug: Casual Game-End game stats not available

At the end of a casual game, sometimes the end-game statistics are present, sometimes the game just isn't there anymore. I'm left not knowing what happened (did they surrender or abandon), what were the final stats like (and what were the per turn stats)?

It leaves an awesome game with a very anti-climactic feel.

Perhaps the casual games can require people to claim their victory rather than just auto-end the game?
