1. Open the editor in a fresh session
2. Create a UMG Widget
3. Create a variable of type TextureRenderTarget2D
4. Turn it into a Array type variable
5. Compile
6. Place it on the Node Graph as a GET
7. Pull off the pin and type "for" as in "for each"
8. Note that there's no hits
9. Create a new Actor blueprint, open it. Create the same TextureRenderTarget2D array in the Actor BP. Pull off the pin, see that there's for-each as expected
10. Go back to the UMG widget, now the for each loop shows up when you pull off the pin.
