cpu stops working

I made a ai that simply follows an invisible block. the invincible block follows the ball. but when the ball respawns the invisible block stops to follow, and then my CPU stops to work as well.

oh and i made the invisble block green to make it easyer to understand

The ai follower is set to follow Ball “Object 143”. When that object gets destroyed, a new one is created, with a new name, and the ai follower doesn’t know about it.

@grazer But i can not make it so that the follower is set to any ball, What should i do?
