console recognizing an old, deleted class, why?

I am trying out various codes and what not in a game/project. The project became cluttered with tons of behaviors etc. so i Have purged them all. Working in the same project tho, because it has all the images I need, I started fresh. However the console is telling me it "cannot unlink namespace parent linkage" for an old class. You see this class, and its scripts, names etc were all deleted, I wanted that, so why does the project still recognize the old, deleted class type?
