For the clean project where I tested it, it is really empty.

/**

UCLASS()
class KOSMOFRONT_API UBTTask_GoTo : public UBTTask_BlackboardBase
{
	GENERATED_BODY()
	
};

As you see I extended it from UBTTask_BlackboardBase, not from MoveTo.

After I renamed it from UBTTask_GoTo to UBTTask_GoToDestination, everything went fine.
