[gameplay] Nasus Q problems

If you try and use Nasus's Q on a minion and then try to switch to another minion instead, it will sometimes make the Q take a very long time to animate and land.

1. activate Q
2. choose a minion
3. cancel the attack
4. choose another minion
5. the animation takes about 4 times longer than normal
6. you finally hit the minion after a long time
