[Has anyone encountered such a problem? The weather data is not displayed after I clicked sync.]

I have the same problem. All aircrafts. 😞
Cannot sync live weather.

[Standard crash at startup and after fast forward with A350]

Seems like it was related to the airframe.
If I pick the one marked in this picture, it works fine.
The other one will cause these crashes.
 

[Standard crash at startup and after fast forward with A350]

Hi! Have you found anything regarding this?
For me the 350 crashes if I choose to start from a gate instead of a runway.
It looks like the plane is randomly placed at the location.
Sometimes it seems to be just a little bit off and avoid the crash, like in the picture.

Regards
