Haven – "Everything is mixed up, truth and falsehood" [Campaign 3 – Mission 2]

I probably have the most idiotic question. I've "killed everyone, only one remains" a long time ago. But in "Quests," the active objective is "Eliminate George." And the mission doesn't end. Although I've beaten that George, and I remember doing it more than once. What should I do? Where should I look for him – there isn't a single hero on the map, neither above nor below ground.

P.S. I found the hidden house, captured the Necropolis castle underground – George wasn't there.
