In my opinion, you should let the customer deceit, if he will this feature or not.
The correct course of action is instead trying to understand why it's crashing only with the Navdata, because:
- If the Navdata has a problem, we should report it to Asobo, so it will be fixed for everybody.
- If GSX has a problem with the Navdata, we should fix it instead of stop using it
One of the replies I posted explained why now the Navdata is complete with Jetway data, and why there's no reason to going back to the old method, I'll copy it again here:
And why you would want to go back to the legacy "airport cache" method, which would:
- slow down the startup
- have to be regenerated each time you install/remove a scenery
- affected by any possible issues in your Community folder, like file access problems, possibly corrupted files or just not finding the right .BGL ?
- not future-proof, because it relied opening a non-officially documented file format, which can possibly change at any time ( it has already changed several times since MSFS came out ) ?
But that's just half of the problem.
The real reason why we let to choose between the Navdata or the airport cache method, was that with the old Navdata, we got even LESS data about Jetways ( with the .BGL, at least we knew where they were) so, while we gained Marketplace compatibility, we got Jetways to be less reliable.
That's not the case with SU12 that, not only give us all the data we had in the .BGL, but it's giving even more data we never had, about the jetway docked status, and its actual position after the animation, this is new and it's so much better to solve a whole category of problems related to GSX not knowing exactly where the jetway docked, or if it docked partially. All clearly explained in the video about the SU12 update.
In any case, you might TRY this, edit the %APPDATA%\Virtuali\Couatl_MSFS.INI change this line:
useAirportCache=0
into
useAirportCache=1
Now, I haven't tested this, so I have no idea if there are issues with it. And, each time you run the update, you'll need to redo that.
