Hi,
When we load the model,few links are not connected to the nodes. Whereas, if we move the node,
links are rerouted and connected as expected. Also,links seems to work fine in smaller screen,but not in bigger screen. Could you please let us know what could be the problem?
Please refer the below GIF 
Does your model include saved routes for the links? How do you load the model?
Model doesnt include saved route points for the links. Model contains info of node ids,ports and links but not route points. Points are calculated from goxam.
That’s really odd. Might the nodes be changing size dynamically without the diagram being notified? Does the problem only happen upon loading the diagram? If so, perhaps a work-around would be to invalidate all of the link routes in a Diagram.InitialLayoutCompleted event handler.
