A timing question.
Snap Wexley can boost action after a 2+ maneuver.
Flight Assist Astromech can free boost or barrel roll if no one is in arc after a maneuver.
They both trigger after the maneuver and can be done in either order.
When do you determine the "no enemy at range 1-3"? Is it after the maneuver or when you check the card some point after the maneuver considering that boost isn't a maneuver?
If the boost from Snap meant you now have someone in arc can you still barrel roll?
Also if you had someone in arc after the maneuver but boosted and now no one is in arc can you barrel roll?
