1) The mission states that "A Rebel figure may interact with the terminal to close the open door closest to the sabotage site." and "Once a door is opened during the mission, it can not be closed again." Does this mean if the Rebels close doors 1 and 2, but then the Imperials force open door 2, that then the Rebels can no longer close door 3?
2) The mission states that "If Darth Vader is targetted by an attack, and there is an adjacent trooper that is a legal target for that attack, that figure may become the target of the attack." If Mak declares an attack targetting Vader at range 4, but there's an adjacent trooper at range 3, does the attack redirect happen before or after Mak decides to spend for Ambush? And if the redirect happens afterwards, would Mak still get the Pierce 2 on the attack on the trooper?
