We've had several users report that there are times where they start flight and our jetways have vanished.
Sometimes restarting the flight allows for the users to see them again.
From our troubleshooting it only appears to happen when the user spawns on a gate / ramp.
The jetway stays visible if the user starts on the runway, on approach or fly's in from another airport.
This also seems to run alongside the strange ground texture error.
