Zombie Object Warning?

Idk whats happening, or if this is even a bad thing, but blender keeps giving me a zombie object warning. I think it may have something to do with the object it specifies being removed from the scene just before it gives the warning. Anyone know what this means?

i had it, i heard it’s something to do with duplicate objects

I remember a thread about this a while ago, do a quick forum search and it should turn up. I believe someone explained what it means.

It happens sometimes when you delete an object but there is still a link to it somehow, especially through the debug show properties setup.
I think that is maybe the only thing that does it.
If you delete something try to make sure it is the parent object so it doesn’t leave any links to itself, and try it with debug settings off.
