Pitch Rotation stucks at [-90 90] C++

[nutellis]

The solution to my problem was:

void ATest::Tick( float DeltaTime )
{
	Super::Tick( DeltaTime );

	if (!SphereMovement.IsZero()) {
		FRotator newRotation = SphereMovement ;

		FQuat quatRotation = FQuat(newRotation);

		AddActorLocalRotation(quatRotation,false,0,ETeleportType::None);
	}

}

Had to remove GetActorRotation and change SetActorRotation to AddActorLocalRotation

The quaternion part is not necessary .
