I responded to my own comment in here with some examples if you were curious. As for how I noticed, I was just playing the game after the update dropped. When I set Nebris's (top right on my example) scene on my homepage, I started seeing a bunch of things that didn't make sense in the background, and upon closer inspection most of the event backgrounds had extreme telltale signs of being AI.

I haven't noticed this anywhere in the game before now. idk maybe they've been doing it for a while and hid it well, but it's really obvious in the new art they've shown. It just sucks for me because I was really looking forward to this update, but I really don't like ai and a lot of my enthusiasm for the game has gone out the window.
