Powerful Blow

Please read my first post again, it states the version of my game and "play campaign again". Appreciate your efforts, though.

Believe me, I've tried that more than once, but to no avail. Now I'm additionally stuck at the 30 crystal quest... with 150 crystals and nothing happening. Grrr...

I've decided to play the campaign again to see how the changes of 1.09 feel, and now I can't get past the Troll quest. I've killed 3 groups of Trolls, yet the sovereign tells me there's one more farm in fear of invasion. Did I miss something?
