It should be possible to set the area for the forester more precisely. Often the forester plants new trees where I do not want them.
You can pick the favored area with the “Focus Point”. The Forester should then plant the next tree as close as possible to the set location.
I know. But the problem is, that I often want some areas left free for buildings. I have no solution for that. But if trees would be just marked as “cut as soon as possible” when I place a building on top of them then this would not be an issue.
