Trophies (Population): How do I get 100 villagers? The game says there isn't enough housing.

In order to achieve populations higher than approximately 90 villagers, you must complete some of the collections. Each completed collection increases your tribe's maximum population by 5 villagers, and completing them all increases the maximum by another 5 villagers. You will need to complete 2 collections in order to achieve a village population of 100.
