It seemed like the moment I took off from the runway, the lady told "aand we're Airborne" but the instructions still said to take off from the runway while I I was in the air.
Later it caught up and I had to climb and it dissapeared a moment later instead of sticking and lighting green when I got to it.
Sounds like a bug yeah. Restarting could solve the issue maybe?
I wonder what triggered the bug. The tutorial is made with a predefined setup so there aren't nearly as many random variables as in regular gameplay.
