Hello. So, I have this little problem with my Behavior Tree: It won’t run when I run a simulation and Steps Back -1 is displayed in the Behavior Tree graph.

I have no clue what happened, as it just popped out of the blue. My Behavior Tree was running fine just yesterday. Furthermore, the only changes I made were to an Enumerator. The bulk of code running the Behavior Tree has remained untouched.

This is the section starting the execution of the Behavior Tree in my derived AIController Class:

void AAI_Hero_Controller::Possess(APawn * Pawn)
{
	Super::Possess(Pawn);

	AAI_Hero_Character* AIHero = Cast<AAI_Hero_Character>(Pawn);

	UE_LOG(LogTemp, Warning, TEXT("AI Possessed"));
	if (AIHero->BehaviorTree != nullptr && BehaviorTreeComponent != nullptr)
	{
		BlackboardComponent->InitializeBlackboard(*(AIHero->BehaviorTree->BlackboardAsset));

		UE_LOG(LogTemp, Warning, TEXT("Blackboard Set"));
		BehaviorTreeComponent->StartTree(*(AIHero->BehaviorTree));
		UE_LOG(LogTemp, Warning, TEXT("BT Started"));
	}
}

Furthermore, the visual logger is not recording any activity on the timeline.
Can someone please help me understand what it means? Thank you.
