I absolutely love this new quest and hope you make the frequency it occurs really high! However, when you accept the quest, it starts a 24 hour timer for the shuttle to leave. Once you arrive at the destination, the shuttle timer resumes at where you left off. This means that if you started the quest with 1 hour left on shuttle then you fail the quest at the destination 1 hours later, and you get stranded halfway across the map. I assume the shuttle timer should reset back to 24 hours
The time remaining on the shuttle is not easy to find either. I could only see it under the active quest tab. Also you can 'fail' in this manner after receiving the quest rewards, which seems counter-intuitive.
Thank you for the report, confirmed.
