In a v0.9 4vs4 team game, my team mate sent messages to another member of my team. I happened to be online at the same time (I had tracking enabled as well) and could read all those messages. I exited and reloaded the game, and these message were no longer visible to me.
Now in this instance it was unproblematic, since the messages where actually meant for the entire team and the sender had not selected the whole team by accident (I guess using the unfortunate reply button). So for us this bug does not need fixing, but this behaviour clearly violates the confidentiality that the message interface suggests - it could lead to awkward moments within teams that are less honest with each other.
