During the game, I find that a player has sent his queen with no escort, as realization comes in, I place my pirate to the task immediately, but as soon as I attempt to target the sub (schedule), it seems to diverge its direction in a very peculiar manner. The direction fixes itself by a switch when the enemy queen goes out of sight, but it becomes too late for my pirate, returning to an outpost soon after. And yes, the pirate does reach the queen before it arrives to its outpost; the queen arrives after approx 11:44 m while the pirate reaches her by approx 10:40 Hrs, almost an hour in difference. View the link below.

Note: Whilst targeting the sub with the pirate, the travel line kept toggling in two separate places with rapid speed, basically, going crazy, from where my finger is, and the pirate's arrival.
