cloning nodes now works much better than in previous releases. Very stable, unless:
-) Clone a Node with Nodes in 1 deeper level (let's name them O1 (original 1) and C1 (clone 1))
-) Clone the Node from the lower level of either the C1 to somewhere else
The connection between O1 and C1 for this child is broken. The connection exists only between the lower level clones, it's not "synchronized" back up to O1.
You can see the behaviour in TF14 in included Mindmap.
