Is this normal? Because when I tried to use Sync to clone myself It just deleted my whole inventory is this a well known bug or is it natural? I personally think this is a bug because i watched a youtube video by AntVenom and he used Sync and cloned himself and if you notice, he had items in his former self and Sync kept the items. Can you tell me if this is a conflict or not? It will be gladly appreciated
