You do not have enough turns to command an immediate move. You need 116427

To move 1 sloop that is 20 minutes away from port? You must be high.

Can you provide more data? Like crew count? Have you lost crew during the upkeep perhaps? What happened eventually?

has happened to me thrice. in fact it happened just now have a look at the port battle at aiora between me and stenley roise . i plundered his brig but it shows the SHIP is travelling and here's what it shows :
IF you wish, you can use your turns to make your ship reach its destination immediately. The cost of the turns is relative to time remaining for your ships to reach their destination.

I remember now. It is not a bug but still we need to remove the Instant travel link from there.

Thank you R0nnie

Awww man, I liked my title... It was rather funny in my opinon. The only true data I can supply you with, is that it was a ship I plundered while it was in mid journey to the port, I believe it had minimum crew and max cannons. I hawked the ship for the mere 20k it was worth... But as I went to put it into my plundered fleet I said screw it, only worth 20k. but anyways I tried to get it insta traveled, it was kinda weird. The instant travel button and new destination button were side by side, with no slash to seperate them. that is all the data I can provide, just letting you know.

R0nnie already resolved this above.

In short, plundered ships cannot be instant traveled.

Why is that?

Because they are not in a fleet yet and instant Travel is a fleet command.

Then why the huge number of turns?
