!GetisActive() ?

Can someone please tell me what this is? It's driving me nuts.
This has no pattern, it happens at random while im developing. Its either on playmode or editor mode and as you can see it has no description of what it means or why it happens.

 

Have you had any luck with narrowing down the line of code causing it?

 

I thought it had something to do with Editor Scripting... but that doesn't seem to be it.
It might be something in my project, but im not sure.
