Comment 1 for bug 1348800

There are three major ways to fix the bug:

1. Changing sigma values in model (0.25 and 12.5 to higher ones)
2. Changing all the terrains and trees (values for affinity)
3. Changing foresters, make them plant only best-fit trees for the ground

First one is the simpliest and it works (https://bugs.launchpad.net/widelands/+bug/1328635/comments/45)
Second one will be also good, but it has to be done by one person (with an idea how to fix)
Third one is most complex and makes foresters thinking :)

Tibor already tested first idea and has something.
Tibor: Please, tell us what values did you use?
