Mandarin Chinese 1 Grammar bot

In Mandarin Chinese 1 Grammar bot keeps repeating the same things over and over. I’ve already repeated how to use “ma”, “le”, and how to answer yes / no questions three times each. Now I’m facing the fourth and I really have enough. This is unbearable. I don’t know if it’s a bug or not, but if it isn’t I really really hate it because I’ve got the concept, but I’m forced to repeat it again and again and again and again and again and again… Completely idiotic.
