I had yesterday off so I spent most of the day playing Civ 7. I was Benjamin Franklin, as Carthage. I was in the middle of a continent and I had Amina on my left side. She had 3 costal settlements and I built 3 settlements in kind of a large triangle. I left a little space because I would otherwise make a city-state hostile due to being to close. Amina decided to build a settlement right in the middle of my 3 settlements. I got annoyed and I went back to an autosave and changed the direction I grew 2 of the towns so she could not do this. Her settler kept just moving in circles, totally confused. Amina didn't build another settlement, the whole age, even though we were only a third through the age and there were a ton of areas to build, yet.
