UTextRenderComponent not changing visiblity for one player.

I have Character set up to show tooltip when he looks at pickup:

void AMyCharacter::Tick(float DeltaSeconds){
	Super::Tick(DeltaSeconds);

	FHitResult Hit;
	FVector StartLocation = GetActorLocation();
	FVector EndLocation = StartLocation + GetViewRotation().Vector() * 200;

	if (GetWorld()->LineTraceSingle(Hit, StartLocation, EndLocation, ECC_Camera, FCollisionQueryParams(GetClass()->GetFName(), false, this))){
		APickup* LookingAt = Cast<APickup>(Hit.Actor.Get());
		if (LookingAt){
			GEngine->AddOnScreenDebugMessage(-1, 10.0, FColor::Yellow, TEXT("i see"));
			LookingAt->ShowTooltip(this);
		}
	}
}

In Weapon_Pickup (child of pickup):

void APickup_Weapon::ShowTooltip(AMyCharacter* ToWho){
	GEngine->AddOnScreenDebugMessage(-1, 10.0, FColor::Yellow, TEXT("turning on text"));
	Tooltip->SetVisibility(true);
}

Problem is - the text does become visible for everyone except the player who i looked at it with, i tested it with multiple different players looking at pickup.

Additional question that i’d like here, because it doesn’t deserve it’s own thread - how to check if character is controled by local player?
