On pages 6,7 and 8 of the new rulebook, it states that ships cannot perform these actions if they would flee the battlefield which agrees with the FAQ update about this.
Now on page 11 in fleeing the battlefield, it says a ship CAN flee the battlefield due to actions that change its position.
I'm confused???
Boost, Barrel Roll and Decloak are actions that make it change position. Well Decloack really isn't a true action as it happens at the start of the activation phase but the other 2 certainly are actions that cause it to change positions.
• A ship cannot barrel roll if this would cause the
ship to flee the battlefield.
• A ship cannot boost if this would cause the ship
to flee the battlefield.
• A ship cannot decloak if this would cause the ship
to flee the battlefield.
FLEEING THE BATTLEFIELD
When a ship executes a maneuver or performs an
action that changes its position, if any part of
its base is outside the play area, that ship has fled
the battlefield. A ship that flees the battlefield is
destroyed.
