There seems to be a bug in the ship flight control. It works OK if you take the default settings, but if you adjust to a specific time of travel and click OK it gives the confirmation screen showing the selected time of travel but when confirmed has a different setting. I just set a flight to last 8 hours and this came up on the confirmation screen, but when confirmed it showed over 10 hours flight time. I have noticed this on several occasions.
This has been known for a very long time.
Not by me - I only just arrived! Pity they don’t fix it because it is really annoying when you try to schedule flights to fit in with sleeping!
I am almost certain that this will be fixed with the next major update after “Populous”, when we revise everything to do with ships and flight.
Thank you for the feedback.
