Hello I want to ask how New creature potion can be used. Before surprise eggs, which I really hate, I was able to use this potion for eggs when I had uncovered places for invrediballs on sacred tree. Now I have free places uncovered but I cannot use the potion. When I use it with regular eggs I get message I can use them with surprise eggs however when I want to use them with surprise eggs I get message that there is no guarantee to get new creature. I have at least 3 places for whole families uncovered so new creature should be guaranteed. What is the purpose of these potions now ? It is rather confusing and I dont like the game so much as before when it was more simple. Now it is only built on luck IF you get regular egg.
