Attempt to manipulate resulted in strange behavior

[dannystaple]

I selected an origin ZY plane of one object, and an origin ZY plane of another. I wanted to align these. In the align on box, I had unticked the Y and Z axes.

Use part/body heirarchy was ticked.

What I expected?

The two bodies, to whom these planes belonged to align such that the planes were coplanar (same X coordinate).

What happened

I see this in the console:

A new object appeared, in my object tree, testCircle. It was not attached to any body. I don't appear to be able to delete these from the UI.

Hmm - I can remove the testCircle (I get a new one with numbers each time I attempt this), but only by goign into another workbench (part or part design).
