Routing page connectors sometimes get messed up.

On the routing page: http://qa-vumi.za.prk-host.net/routing/
I move a conversation block from the button of the right hand column to the top
I change connectors from one end point to another
I hit the 'save' button
Nothing seems to happen
I go back to the dashboard and then back to the routing page, and my changes are lost.
