Description

One-time crash occurred when changing the color value in the Color Picker for a variable.

So far I have not been able to reproduce this issue again.

Steps to Reproduce
  1. Open any project in editor.
  2. Create a new blueprint and open it in editor.
  3. Add a Linear Color variable.
  4. Compile the blueprint.
  5. In the Details panel for the variable, click the color bar.
  6. In the Color Picker, click and drag the color wheel to a shade of blue.
  7. Click and drag in the verticle Value slider.

RESULT

One time crash occurred.
