Description

When a connection from processor A to B is redirected from A to C and A to C already has a connection, then the two connections overlap. The user is not able to see that there are multiple connections. This problem doesn't occur when creating a new connection from A to C (see GIF attached).

 

The path of a connection should be calulated the same way when redirecting a connection as it is when creating a new connection. 

 

Besides:

Why is it not allowed to delete a connection of a running source but to redirect it to another destination?
