For loop with custom event and format string - internal compiler error

This looks to be a similar issue to : Blueprint compile fatal error, only using Print String test loop. - Audio - Unreal Engine Forums
I can reliably reproduce the issue with a new project.

  1. Create a custom event.
  2. Drag out to from custom event create a for loop
  3. Drag out for loop’s “index” and call “to Text (int)”
  4. Drag out “To texts” return value and call a “format text”
  5. Add a pin to “Format text”
  6. Drag a second pin from “To texts” return value to the newly created pin
  7. right click on “Format Text” first input pin and break the link to “to text”
  8. In “format Text” first pin (now a textbox as you broke the link) enter any text
  9. Click anywhere or compile and it will crash

To fix the issue you have to remove the custom event and the for loop. If you just remove the forloop you will continue to have problems despite it compiling.

Hi BlueByLiquid,

I apologize for the length of time that this took to respond, we concentrate on the Bug Reports section and this was overlooked in the blueprints section in the process so I moved it over. It seems that this post was overlooked. If you are still having this error, please let us know so we can attempt to assist you. Thank you!
