So, I solved all my puzzles, had the maximum villagers for my found collectables and was doing fine on maintenance just waiting for more of the collections to fill out. But, I had a lot of villagers that were all the same age. As time went on, I couldn't add more children since I was at the maximum. When a bunch of the villagers died of old age and I was finally able to breed again, that left me with no females under 50. I'm now down to 32 villagers and hoping to get an event that will bring in a breedable female. We'll see how it goes!
