From time to time in PQ games my units -stationed in cities - will start to disappear. It does not happen to units in the field. Once it starts it keeps happening until there are no units in towns at all.
I have checked the following:
1. I have plenty of food and money.
2. There are no adverse global spells against me.
3. There have been no attacks against those cities.
4. There have been no major negative global events.
So I can't figure this out. Does the game have a unit number cap?
I am using and iPad Air 2. I sent my save game about an hour ago.
I would appreciate any help you can provide.
