Events following the player?

And by this, I mean other than when I want them to.

To be specific, I have an event that's essentially playing hide and seek. It's a single event that teleports to a different place on the map each time you find it. At one point, he disguises as a tree, which is the point where it starts to glitch. The screen darkens for a while like its supposed to, and while it's dark, I use the "Set Event Location" to give him a new hiding spot (and in the last 3 instances, change his graphic.) However, in the last 3 instances, he essentially attaches to my character. He does not turn and remains in the same relative location to the player. And he won't go away unless I leave the map or get close to where he's supposed to be.

SCREENSHOTS:

It would be Easier if you make 3 seperate events rather than using "Set event location"

Here's a event sheet for you

Make three to four blank events and use the example above.
