HelpMonster Player Detection

So I was testing on my serer when I noticed this.
You can see in this first picture that my alt is in the middle of the nexus.

But very far away an enemy is still shooting at him.

Why does this happen, and how do I fix it?
(Also I know that it shoots weird. I'm gonna change it.)

If.Instance(
IsEntityPresent.Instance(<distance>, null),
//do something
)
try that

Simple simple answer see that line ?
Cooldown.Instance(1000, MultiAttack.Instance(100,blah blah blah)
That first number is the RANGE
Range = the Range that it will detect the player

To fix place like 15 for big bosses like Thessal
How i did look over and see i don't have any more than 20
