Troubles with TGB's "cloneWithBehaviors()" func

Howdy:)

Whenever I call "[t2dSprite].cloneWithBehaviors()" it generates this error message in the console:

///////////////////////////////////////////////////////////////////////////////////////////////
t2dSceneGraph::addToScene() - Object '1593' is already in a SceneGraph!.
t2dSceneContainer::removeSceneObject() - Object 'Always Scope' but not in Scope-List! (1593)
/////////////////////////////////////////////////////////////////////////////////////////////////

Generally, this wouldn't be to much of a problem, except that my game is very "cloning" intensive: after several minutes of play, the console gets pretty big (I played for 8 min or so and the console size ended up around 150 KB).

I took a look at the "Behavior Playground" demo, which uses the same function, and it generates the same errors.

Any help, suggestions, ideas, etc. would be greatly appreciated!
Thanks
