When dragging ‘Player Controller’ from the input of Logout the editor shows you dragging from the output ‘Player Controller’. Choosing a method after dragging out such as ‘Get Player Controller’ still correctly links result to input node.
I was able to reproduce this issue on our end. I have written up a report (UE-32211) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
