Please help me, someone, I'm already tormented. I'm playing a single-player game on the Valguero map, I found two wyvern eggs and pulled them out, then when they gave me an egg, I raised it with 100% affection using Crazy Crazy's potion, but every time the child has stats exactly like the parents, everything works fine on other creatures and only the wyverns have such a problem that am I doing something wrong and how can I fix it? (Sorry for the mistakes, I don't know English well through a translator)
