NWNX_Creature_RunEquip Segfaults if called right after item creation

[Aschent89]

This server crash seems to be new as of .35+ as my use of NWNX_Creature_RunEquip had no issues prior to upgrading.

In practice, I would run NWNX_Creature_RunEquip in a few spots similar to below:

        object oOriginal = GetItemInSlot(INVENTORY_SLOT_CLOAK, oPC);
        object oNew      = CopyItemAndModify(oOriginal, ITEM_APPR_TYPE_SIMPLE_MODEL, 0, nNewValue, TRUE);
        if (!GetIsObjectValid(oNew))
        {
            SendMessageToPC(oPC, "Something went wrong, aborting.");
            return;
        }
        DestroyObject(oOriginal);
                // NWNX_Creature_RunEquip HERE
        SendMessageToPC(oPC, "Appearance #: " + IntToString(nNewValue));

Doing the above would result in a server crash (backtrace below). The temp solution to this is to lock the NWNX_Creature_RunEquip behind a separate function that includes a DelayCommand:

void _equip(object oPC, object oItem, int nSlot) { NWNX_Creature_RunEquip(oPC, oItem, nSlot); }

What about using vanilla nwn functions to equip?

    int iSlots = INVENTORY_SLOT_HEAD & INVENTORY_SLOT_BOOTS & INVENTORY_SLOT_ARMS & INVENTORY_SLOT_BELT & INVENTORY_SLOT_CARMOUR &
                 INVENTORY_SLOT_CHEST & INVENTORY_SLOT_CLOAK & INVENTORY_SLOT_CWEAPON_B & INVENTORY_SLOT_CWEAPON_L & INVENTORY_SLOT_CWEAPON_R &
                 INVENTORY_SLOT_LEFTHAND & INVENTORY_SLOT_LEFTRING & INVENTORY_SLOT_NECK & INVENTORY_SLOT_RIGHTRING & INVENTORY_SLOT_RIGHTHAND;
    object oSlot = GetItemInSlot(iSlots, GetEnteringObject());

    // Unequip & Re-Equip all items to fix nwnx_haste bug.
    AssignCommand(oPC, ActionUnequipItem(oSlot));
    AssignCommand(oPC, ActionEquipItem(oSlot, iSlots));
