give it another try -_-

it did not work... @Motu its bugged... anyway it works now (this time i'm
certain. I tested it.)

So adding "player.spell(Silencing Shot).cooldown = 0" should have stopped the hunter from stopcasting (that is caused by the s in interrupts) because it should return false. and it does... however the s in interrupts still does stopcasting. thus interrupting the hunter every time the target is casting.
