Widget Blueprints Fail to Compile When Copying Collapsed Graphs into Functions

Collapsed blueprint nodes that are copied and pasted into a function graph of a Widget will cause a fatal error when the blueprint compiles, as seen in the callstack, and will provide the message: "Statement tried to pass control flow to a node Inputs that generates no code" in the widget's compiler results window.

• Create a new Widget blueprint
• Create a collapsed graph node that takes an object reference input. does something with it, and finally returns an object reference.
  •  Example:
  • [Image Removed]
• Copy that collapsed node from the event graph of one Widget Blueprint into a function graph of another Widget Blueprint. (Using Ctrl+c & Ctrl+v)
• Connect the execution pin
• Attempt to compile the target BP, and notice the fatal error that occurs
