AddProceduralMeshComponent node throws UnknownTemplateReferenced errors in duplicated Function

User description:

1) Make a function that has a Add Procedural Mesh Component node. 2) duplicate function 3) open duplicate and delete the add procedural mesh component. 4) go back to original, it's not add component and won't compile.

I get this error:

Error Unknown template referenced by 'Add Component Target is Actor' for Add Component

1. Open QA-Game
2. Create an actor class BP & open it
3. Create a Function & open it
4. Add an AddProceduralMeshComponent node
5. Compile
6. Right-click the function in the MyBlueprint panel > Duplicate
7. Open the new Function
8. Delete the AddProceduralMeshComponent node and replace it with another of the same node
9. Compile the bp

Results: The original function will throw an [Unknown template referenced by 'Add Component Target is Actor' for] error and will not compile

Expected: For the bp to compile correctly with the new node in place
