occupied

I conquered a city state (in this case Buenos Aires) and it is occupied. I wondered if it might have to do with their previous owner as they had been conquered before, but they have no claim anymore. In a weird series of events they were conquered by Rome, I liberated them for the Australian...

I took a city off Harald in my game started post patch. When we made peace, asking for him to cede the city was not an option. He is still denouncing me for occupying it.
