I could look further into it on my system, the windsocks and the trees work fine for me. I set the winddirection to 270 degrees and the sock and the trees follow the correct direction as you can see in the following screenshot, looking in the direction of 270 (the runway is 09 and 27):
But the wind turbines are set to a fixed wind direction from the north, the don’t move if you change the wind direction…
