Fog or mist

I am still getting used to TANE - looks very impressive so far - but one thing that has been bugging me (excuse the pun) is on all routes and scenarios I have tried so far, there is a lot of what looks like to me as being good weather fog and I have been unable to find a setting to turn it off - is this a permanent feature built into the routes?

This is going to be fixed in an upcoming patch some time soon(tm).

To turn off the fog you go to Surveyor and choose edit environment, just like in TS12.
