It has standart jetways that are operated with CTRL+J. What may cause this? In a long period of time the only change that I did in my sim was updating the GSX.
It depends if they used the default model or not.
It's very unusual for a 3rd party developer to use the default model, but if they did, they would be *disabled* AND *replaced* by GSX SODE model, just like in a default scenery. A CTRL+J that use a custom model CANNOT be replaced automatically by GSX: you must do all the following to exclude them:
- Create an exclude area with the GSX parking editor. This would cause a GSX/SODE jetway to appear on top of the old jetway.
- Exit the sim and launch the GSX Control Panel
- Compile the exclude file for that airport.
- Restart the sim. This should result in the old jetway removed, leaving only the GSX/SODE in place.
The only possible way that it might be related to having used GSX and ending up with NO jetway is if you DID all of this, then you uninstalled GSX Level 2, so the jetway is not visible because your Exclude file is still there (the GSX uninstaller won't remove your own Exclude files), but the GSX replacement is not there anymore, because you uninstalled GSX.
If that's not the case, there's no way the jetway disappeared because of GSX.
