Don't know if this is necessarily a bug or not, but I've played 2 games since release where I've noticed my closest neighbor (150+ turns in) not cutting forest/jungle to build plantations on (all) available resources. First time I didn't even realize until I invaded their territory in late game, but in my new game It's happened again.
BUT...
The second time I can at least put some reason behind the AI, as they picked Goddess of Renewal and chose to leave forests jungles intact after they built the first plantation to connect their resource. I just don't know if it's a bug or intended strategy, and either way it was the wrong decision in the specific game as I was Hiawatha and used the forests/jungles to conquer quite easily. Is anybody else seeing this behavior from the AI?
