Unable to Read memory of property on Blueprint still in the game

Development Programming & Scripting

So I’ve massively simplified it to take arrays/objects out of the equation, and just use an int:

void AResourceManager::BeginPlay()
{
	Super::BeginPlay();
	MyNumber = 555;
}

Then when later read:


FResourceInfo* AResourceManager::Find()
{
	MyNumber = 333;
}

Throws when reading MyNumber:

Exception thrown: write access violation.
this was nullptr.

MyNumber is a UPROPERTY in the header file. When it says ‘this’, does it mean MyNumber, or the instance of the class it’s executing itself?
