When duplicating a collapsed blueprint graph which has a node with a custom Exec pin, this results in blueprint compilation error that a duplicate named pin is found. Duplicated exec pins aren't assigned unique names (nor guid, it seems).

User that reported the bug suggested a fix as well, see linked case. I've made a short repro vid too, see attachments.

Steps to Reproduce
  • Have a collapsed node
  • Collapsed node contains a node with a custom exec output pin
  • Internal custom-exec-output-pin node should be connected to the execution flow, so that it gets compiled.
  • Copy-paste the collapsed node. Both original and copied node should be part of the execution flow, so that they both get compiled.
