In my village 2 of my villagers got kids. These kids later also got kids, which are the grandchilds of the 2 original villagers. These grandchilds had spent a lot of time visiting their grandparents (the original villagers) in their house, since grandparents are happy when they see their grandchilds. However now they stopped doing that, which makes the grandparents sad. I have no idea whats causing this so it is probably a bug. Can you fix this bug? I want them to visit their grandparents again!
