I've had this happen pretty consistently. An example of what's happening is that I might have a character I'm animating, and I've made a hand a child of the character's arm object, so when I rotate the arm, the hand moves with it.

I have the hand nested in its own container within the arm-parent (for Android animation reasons). I take that nest, with the hand in it, and duplicate it. So, now there's two nested groups, each containing a hand, as children of that particular arm.

I then drag and drop that nested group onto the opposite arm, to make it a child of that opposite arm, and Sencha immediately puts up an error message saying Send Report or Don't Send Report. I have to restart Animator to continue. When it restarts, the Nested Group I'd made by duplicating the first Nested Group (with hand object) is in the right place, as the child of the opposite arm, and I can continue animating.

Obviously, the expected outcome would be that I could drag and drop the nested group, with no

I'm hoping that you'll be able to reproduce this on your own computer.
