Thanks for reporting!
There was a probability of Magic Fruit success which decreased with the amount of the eaten fruits. Although we forgot to write about this in the item description. After some consideration, we decided that it's too harsh to fail the Magic Fruit effect completely. Now they will always give 1 point if failed (otherwise there's a chance of getting up to 3 points).
We can change the formula back in the future if it will ruin the balance. +50 points is quite a serious bonus, here's the average stats of a pet with any genetic or magic boosts:
We added some magic fruits to your inventory to compensate our oversight. Sorry for the confusion.
