For my own knowledge I write down the number of people and culture per town most days I play. I seem to have lost a number of people and culture in three towns since yesterday. The fourth and latest town (build approx. 6 days ago) was exactely the same.
Any one else this problem?
In town 1 I lost 4 people/20 culture, town 2: 6 people/9 culture, town 3: 5 people/18 culture.
