Hi.

(UE 4.27.2)

I try to to make the name of my UInstancedStaticMeshComponent unique by adding a random number to the name. After a lot of testing, I figured out, If if use any random function, the OnComponentHit not return with hit event.

Here is the code, how I tried to generate a random name:

if (GetOwner())
	{
		FString ownername = GetOwner()->GetName();
		uniquename =  "_"+ownername;
	}
	else
	{
		int random_value = FMath::RandRange(1000, 9999);
		uniquename = FString::FromInt(random_value)+"_A";
	}
	
	//PrimaryComponentTick.bStartWithTickEnabled = true;
	Root = CreateDefaultSubobject< USceneComponent>(TEXT("Root"));

	RootComponent = Root;
	
	FString rawsidename = "Instancedchainlink_side" + uniquename;
	FName sidename = FName(*rawsidename);
	
	//Instancedchainlink_side = CreateDefaultSubobject<UInstancedStaticMeshComponent>(sidename);

The problem is not the name itself, I copyed and added the string manually (Instancedchainlink_side2893_A) to the name, and the event fired. Even weirder, if I added the number to the random_value variable, it also worked perfectly.

Any idea why is this happen, or any workaround. Maybe an another method to make my Instance name unique?
