Description

The editor is crashing when dragging a TextRenderActor BP with a Set Text node in the construction script.

Steps to Reproduce
  1. Create a new BP based on TextRenderActor and open it
  2. Switch to the Construction Script tab
  3. Search for and place a Set Text(TextRender) node
  4. Wire the construction node to the set text node
  5. Right click on the Value pin of set text and promote to variable
  6. Compile the BP and fill in a default value for the created variable
  7. Back in the main editor drag an instance of the TextRenderActor BP into the viewport

Result: Editor crashes
