Describe the bug

I was flying from Frankfurt to Abu Dhabi and everything went well until the A380 started to fly big circles in the rumanian airspace. All the displays showed that I was following the planned route and that I am flying the correct heading. Also the horizon was leveled. Only in the outside view you can see, that your flying a bit angled.
I was able to put a new direct into the flight computer but that didt change the aircrafts state in the air. Disconnecting the autopilot and flying manually didn`t help either. You can see how the sidestick is moving but the aircraft is not reacting to the inputs. The circles are not controlable and I had to abort the flight.

Expected behavior

Because everything else of the flight went perfectly fine, I expected the aircraft to follow the route. There was absolutely no reason for this behavior of the aircraft.

Steps to reproduce

1. Departing in EDDF
2. Using the autopilot
3. Following the planned route without any extras (e.g.: no direct by ATC)
4. Cruising at FL390
5. The bug came out of nowhere

same issue

I believe this issue is the same/related-to #9215 and #9341

What you describe is exactly what happened to me on my first flight...

yes this sounds like a systems crash as such it is a duplicate
