Need help asap with script when its stuck

Hello, im using a forbidden hydra land script, everything is perfect except that when it comes to the npc to travel to forbidden land, he says "hi" and then travels to forbidden land.
And here is where the problem comes, it just try to travel again and again, even if it is at forbidden lands, it just stays and says "hi" and then wait little then "hi".

Is there any way to fix so when it is at forbidden land it skips to next waypoint? so its not thinking it is at npc anymore.
