This error occurs when trying to rename “Anim Graph” Functions category while the animation is running in a blueprint animation. It happens regardless if the player accidentally double clicked on the word, “Anim Graph”, as shown in the image below. The mouse is located at the word, “Anim Graph”. Upon renaming it, it will 100% crash and may stall Visual Studio 2013 if VS isn’t immediately in focus.
