Lux Bug

I've noticed a bug with Luxanna Crowngaurd and replicated about 3 times in one game. The bug is if you Q 2 minions and the Q kills them that Q is able to hit a champion and only 1 champion. however if the Q doesn't kill the 2 minions on contact it only hits those 2 minions. So something is allowing the Q to keep going after instant killing the first 2 minions on contact as if the snare doesn't go off on them just the damage goes off.

First minion must die first (on contact) second minion must die (on contact) (nothing gets snared) you see a snare animation still flying if it hits a player AND ONLY A PLAYER it snares them.
