Haven – “Defeat and Victory” [Campaign 3 – Mission 4]

It's frustrating to have to start a map over. All that's left is to kill Arriban.

What patch are you using? I have my save file right before the battle with Arriban – I can send it to you; I'm using patch 1.8.

As promised, here's the Save file before the battle with Arriban – Anton has an impenetrable Guardian's breastplate (lasts for 3 turns), he's developed to level 30, and his army shines as brightly as Anton's armor!
The battle took place on the 6th month, 1st week, and 5th day.
By the way, Anton took this breastplate with him into the final mission!
