As you can see in this image, the wires are not rendering properly when flowing in reverse (through reroute nodes at least)
Forgive me if this is well known, I struggled to conjure search terms that identified this issue and as result was unable to find a duplicate report.
Hello KWS,
I have written up a report ( UE-17341) 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.
Make it a great day
I hope they improve this. It bothers me too.
