This rating is so low because a recent update that went out decided to take one of the in-app purchases and reset it for everyone (yes, intentionally, not because of a bug). This means that to retain the same benefits that existed prior to the update, it would need to be repurchased again. This purchase was never advertised as something that was seasonal or temporary. That decision is very devious and damaging to anyone that once enjoyed the game. Unbelievable.
