The wonderful "Dreadlords arrival" is plaguing my current game. They have a battleship running around that has something like 585 attack in Mass Driver, no defenses at all, and 67 HPs. It's pretty easy (even at my early tech level) to build a fleet that can knock it down to zero. Of course, my fleet gets annihilated. And the Dread Lord ship wins every tie, regardless of whether I attacked it, or it attacked me.
So, in Twilight of the Arnor (1.96), what are the rules for who wins ties?
Bonus question, why was it considered necessary for anyone to win ties? If two fleets wipe each other out, well, then they wipe each other out, what's the problem?
Thanks
