I have created a flowchart with a number of boxes (of different types) and connectors between them. When I re-open the document after a prior edit and save, many of the connectors have moved. What I mean by that is that they remain connected to the source and destination boxes, but that the path that they take moves. Connectors that are a simple straight line do not. Nor the ones that only have a single change of direction.
But the ones that have 2 or more changes of direction almost all move (from the variations I had made) back to the centre position - even if this is over the top of an unrelated box.
Is there some way to prevent this? Or is this a bug?
