No trees :(

[Buchon]

This happens to me.

The tree configuration in game dont work sometimes, the game save the changes in the conf.ini located in your documents folder, but the game read the tree configuration located in the config.ini located in the Steam folder.

Goto your x:\Program Files (x86)\Steam\steamapps\common\il-2 sturmovik cliffs of dover folder and open the config.ini, then set Forest=1

Edit :

Dont forget switch off the cloud syncronization in your Steam settings before.
