Cameni, I have black screen after the update ...
Airport area is full of spikes. If some have black window just reset graphics settings, it will black issue
Just by curiosity, are you guys under W10?
I noticed UAC is really messy with full screen programs, and after an Outerra update the UAC will prompt the "yes/no" window to authorize the install of the update, but will lock me in the full screen program (in a black screen). So Outerra will restart, but without installing the update (check your version number).
You can fix it by running it in window mode or by opening the Task manager in parallel and alt tab to it when the UAC pop-up.
Edit:
Small tip, you can zoom-in/zoom-out now in the Cessna and the Mig using +/- numpad keys
