Fix cell-change crash caused by use-after-free of BGSAttackDataMap

[miredirex]

Assigned here during TESNPC::Initialize()

TiltedEvolution/Code/client/Games/Forms.cpp

Lines 55 to 71 in 20b44d3

	void TESNPC::Initialize() noexcept
	{
	auto pPlayerBaseForm = Cast<TESNPC>(PlayerCharacter::Get()->baseForm);
	// These values are all defaulted, if the other actor did not modify them they won't be loaded, therefore we need to force them before load
	attackDataForm.attackDataMap = pPlayerBaseForm->attackDataForm.attackDataMap;
	npcClass = pPlayerBaseForm->npcClass;
	combatStyle = pPlayerBaseForm->combatStyle;
	raceForm.race = pPlayerBaseForm->raceForm.race;
	outfits[0] = pPlayerBaseForm->outfits[0];
	#if TP_SKYRIM
	spellList.Initialize();
	#endif
	// End defaults
	flags |= 0x200000;
	}

^ Notice how attackDataMap is taken from the PlayerCharacter singleton and assigned to a remote player's TESNPC. When that TESNPC unloads, the game (supposedly) tries to deallocate its resources, including this map

Changed raw pointer to a NiPointer which uses refcount, saving us from the crash
