i couldnt find any specific responses to this, please bear with me
1. can each of my cities perform a different city action during city management. Eg one city harvests resources and my other city devotes to the arts
2. can you stack army figures in a city as part of your defence (according to stack limit). if not do you defend city with only three units
3. When attacking barbarian village with more than one stacked army figure do i still fight them with three units
