Return node pins lose connection after copy and pasting

If the user copies and pastes nodes connecting to a return node in a function then the pins on the return node will become disconnected.

1. Open the editor
2. Open the level blueprint
3. Create a new function
4. Create the blueprint in the attached image
5. Copy and past everything connected to the return node and the return node itself
6. Notice that the vector pin becomes disconnected

Expected: The nodes would paste exactly how they were copied
Result: Pins connected to the return node become disconnected
