4.0.10のアップデートで、「金の卵」がバインド済みに変更されるみたいです。 Golden Eggs, which you can obtain on Miller's Farm, are now bound to your character on Pick-up and can not be traded anymore. あと、それに関連するクエの報酬も変更されるみたいです。 Quest: "An Easy Lay?" Upon the first completion of this quest, you receive 1 Golden Egg and 1 Miller's Special Cake. If you repeat this quest on the same day again, you receive 1 Miller's Special Cake. So you can receive 1 Golden Egg per day by completing this quest.
