[GAMEPLAY] Bug with Xin's Q and Sated Devourer

When you have Sated Devourer and use Xin's Q to attack something that can be affected by the double strike of the Sated Devourer, the knock up on the Q occurs on the second attack. Assuming that the double strike of the Sated Devourer is the root of the problem, I haven't been able to determine if the bonus damage from what would be the third Q strike is negated, or simply compounded into the second attack.
