I did not understand why ship did not come out, explain mechanism of this process.
If you had 1 durability left and got sunk then the ship is gone.
If you have purchased insurance from TA you got a dbl amount added.
I will explain simply, next to the course of the ally's ship when escaping disappears... I'm already swimming to the edge of the map from the chase and see that I'm alone. I'm using the Abandon ship skill.
Sounds like you are in open sea combat.
Escape points cannot be used if you are 'in combat'
If you use the abandon ship skill, then you do excactly what it says - abandon ship
(Give up, leave, loose ship)
