I was doing a flight from Heathrow to Madeira when i was on right base for runway 05 i was turning base and out of nowhere i just landed on invisible scenery at 1900 feet and then i somehow took off from it but 30 seconds later i crashed into nothing in mid air. It was a 3 hour flight so i lost a bit of the xp from crashing. I think it is invisible scenery, a bug/glitch and i think only the devs can fix this.
In case you need to know, i was running it on a Samsung Galaxy S6 Edge and its a bit less than a year old. I didn’t use any apps like in flight assistant or anything like that.
Hope this helps and if you know its not a bug but just a glitch and you know how to fix it, please tell me. :)
