I just saw the Battle Report about the Battle fought be Incitatus. I did not realized that his avatar was not present in Celtic Punks army. And because CP couldn't fight the battle then it should've been autoresolved! The Rules are pretty clear about that.

At the moment no one will get battle points from this battle but I'm not sure this will be the only punishment. I'll think about it. If you people don't want your avatar to be attacked when you are away then make sure he is out of touch from enemy armies until you come back.
