So, I noticed a huge population and happiness spike at turn 137, so I decided to document the whole thing. I am making a separate thread in hopes of seeing others reporting similar finds and getting some badly needed answers - bear with me.
The only notable event is that I got the notification the Epeiros reemerged. Otherwise, business as usual. A couple of buildings got finished - a school and a market.
Turn 136 - things are normal.
Cities: Alali, Atig, Qart -Hadast
Turn 137 - I get word that Epeiros is back and things get crazy. Same cities. I made a save game.
Turn 138, things are back to normal. Same cities.
It would appear that the population increased normally, and that my profit stayed the same, despite the crazy projections.
When I loaded a save game back to turn 137, things were normal. As if nothing happened.
My question is - how do I proceed? Do I keep playing the campaign?
How is this related to faction reemergence?
