[GAMEPLAY] Katarina Shunpo Bug

When Tristana casts Buster Shot (R) on Katarina, but Katarina uses Shunpo (E) on Tristana before the Buster Shot animation is completed, she will be knocked back from the distance she was at before she used shunpo.

EG. If she was at max range (700 units away), and used Shunpo at the same time as tristana casts Buster Shot, she will be knocked back 700+ (600/800/1000) depending on Buster Shots level, Instead of (600/800/1000).

This Occurred 100% of the time in my last game.

Here, the first one is how far she is knocked back without using E (how far it should be), the second is how far she gets knocked back right after using e (way too far). http://imgur.com/vjJcYQt http://imgur.com/of6Lvff
