there's nothing to worry, the "object not placed in world" means that an object got created but without get placed somewhere. So the object virtually "doesn't exist" and the server will remove it on worldsave. Usually its caused by scripts where you use SERV.NEWITEM but don't equip this created item on an char, don't bounce it to an container and don't place it on ground, so the object is created but still not placed on world

and the "mislinked item" error on spell memories usually occur when an NPC cast some spell that will add some effect on the target (eg: feeblemind, curse, bless, poison, etc) and later this NPC die. So the spell memory still equipped on the target but the caster NPC doesn't exist anymore, resulting the "mislinked item", where this memory will be removed on worldsave
