Testers needed.

By the way, it's extremely difficult on Veteran difficulty. I'll write a comment on the fourth map a little later; I really want to finish it. And for now, what are those strange green clumps scattered around the map? Are they needed for something? And one more thing: the closest (left) pile of sand near the Yarrow town is inaccessible – you can't collect it. It would be good to fix this, otherwise, there's no point in fighting its guards.
