If Carenado didn’t change their plane, and Asobo released an update to the sim which made the plane that didn’t change stop working, then the sim change broke it.
But, if the sim, which we should remind ourselves is in a constant state of flux, had something changed which means that Carenado’s way of doing a thing is no longer valid according to the SDK, then Carenado have to rejig their plane so that it is valid.
Asobo will have valid reasons why they implement certain changes, and they can’t go rolling back any change that conflicts with a 3PD’s work otherwise we’d never get anywhere.
