Duplicate Collapsed Graph Loses Variable

UE 4.9.2
I use a lot of collapsed graph, i noticed that complex one cant get duplicated without loose connection with variables.
as you can see the SET nodes go grey and once compiled, even if all is already perfect you get the "Unable to find local variable " and so , all the nodes attached to those variable that go grey give you “Dependency Cycle Detected.”

You can fix all just placing a new node “Set , angle to check” in the same place.
But sometimes unreal crash during the compiling, and to get back your project , you have to reload a previously saved blueprint.

Hello Est_engine,

I was unable to reproduce this issue on our end. I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you provide screen shots of the blueprint that show more of how everything is set up to help understand you setup?

Hi Rudy ,
i can replicate it , tested right now.
New project, black , with content starter. here is the screenshot of this new test .
The lower screenshot show the duplicated graph.

I was able to reproduce the issue on our end. I have written up a report ( UE-23027) and I have submitted it to the developers for further consideration. As a note I found that this can also lead to a crash by right clicking and creating the grayed out variable into a local variable. This has also been placed into the report. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.

Make it a great day
