UPROPERTY(EditAnywhere, Category = SomeCategory) float someProperty1; UPROPERTY(EditAnywhere, Category = SomeCategory) float someProperty2;
UPROPERTY(EditAnywhere, Category = SomeCategory)
float someProperty3;
*Note that property values are no longer set after hot reload*
Result:
Editor will crash during shutdown process
