Hi Matt,
Well, it is “technical” possible, as you have seen.
What happens here was, that the casing was moved, then it was set were it was initially parented to it self [which means to the same position of course as it is at the moment], and so it was on the place where you didn’t want to have it. It is just a wonderful source for trouble.
But yes, I would not suggest that.
Enjoy your weekend
