I use StorageUtil to set outfit just as :SetFormValue(ActorRef, "OldOutfit", (OldOutfit as form)) ,outfit OldOutfit = GetFormValue(ActorRef,"OldOutfit") as outfit.
It do work.
but when I use StorageUtil to set LeveledItem :SetFormValue(ActorRef, "NewItem", (NewItem as form)) , NewItem = GetFormValue(ActorRef,"NewItem") as LeveledItem.
It don't work. return Newitem is null.
Can you help me?
