I succeeded to bypass the 30-heart reward 'cheating detected' bug (I don't know how but I did) but now I have a random power rewards.
I mean by random than each time I refresh the game, the rewards change
And then also I already got it 30 hearts rewards it is the following one that becomes random and I don't know if that's normal or not but it seems strange to me because anyone else could take advantage of the random to refresh the game and change it
