weird winter clouds in 4141

That's the ice wall, i noticed it on the NWEurope map as well, it used to go up about 100 feet, and not it's all the way up to heaven, as your photo shows.

I am using a clean install, it's there in the game, not a mod anomaly.
You can only see it from low down, at alt it goes away or blend seamlessly into the horizon.
