zombie object

i have an object in my project that is being called a Zombie object in the console. The object IS doing what its supposed to do(it only seeks another object). What does zombie object mean?

thanks for the help

It means that you are refrencing to an object that has been removed.

By that I mean that:
A script is searching through a list of objects, looking for the name of the one that has been removed
A trackTo actuator tracking to an ended object
and stuff like that

I think…

the object only uses logic. It Always => seeks another object. to keep its distance from getting to great. It works right. But the objects is permanent. It doesnt end or begin. And it uses no python

Edit: And the object it is seeking is also permanent.

Usual cause:
Displaying the debug properties of an object that does not exist anymore.

And it’s unlikely to come from any object still working and visible on screen (that would be a weird blender bug). It’s probably some other, maybe unrelated, object.
