I see the issue where when you exit the seat, walk around the cab, then sit back down then the train reverts back to a different brake type hasn't been fixed for 2020. To see it in action, get in any loco with multiple brakes (for example class 66). It's set to direct/straight air (loco only) but as I have wagons on, so hit X on controller to change to Auto (train) brake. Get out the seat (Y button) to enable AWS and DSD, sit back down (Y again) and the loco has reset to straight air brake. Really flipping annoying, especially if you don't notice straight away
