Lorsque je vais sur un slime avec comme nbt Size:2, NOAI:1, Invicibility:1, un tag pour qu'il ne despawn pas et un effet Invisibilité très très prolongé (Je suis désolé de ne pas me souvenir de la commande de summon et je ne sais pas s'il se passe la même chose avec le slime simple) je reçois cette erreur:
