Zodiac.. Crashed by a Bush..

[Yen]

... This morning, Zodiac was crashed by a bush.
Directly from /stats:
1. 40.037491666 % npcs[128] (in level zodiacworld_am15.nw at pos (34, 20)) (bush)
The second NPC was the class 'leaps,' which is created when a bush is destroyed, at 9%.

I'm thinking it was done by a modem tap... But anyway, could anyone look at this script and tell me what may have happened or ways to prevent modem tapping?

PHP Code:

function onCreated() {
  this.dead = false;
  setimgpart("zodiac_bush.png",0,0,32,32);
  setshape(1,32,32);
  drawunderplayer();
  layer = 0;
}

function onActionProjectile() {
  if (this.dead) return;
  for (this.a = 0; this.a < params[2].size(); this.a++) {
    if (params[2][this.a][0] == "wepeff") {
      if (params[2][this.a][1] in {"slash","piercing"}) {
        CutBush("slash");
        break;
      }
    }
    if (params[2][this.a][0] == "magic") {
      if (params[2][this.a][1] == "fire") {
        CutBush("fire");
        break;
      }
    }
  }
}
