I got fully deluded by border policy today.
In my previous game session, the AI in the ancient era entered into my city borders and got trespassing status, while I got grievance against him. I don’t remember if he was expansionist, but otherwise he wouldn’t the get trespassing status. Therefore, I thought that now we can freely pass the borders, but get the grievance and tresspassing status, as it was on open devs before, and I was happy for it. But now, on my latest walkthrough, when I entered the 2nd era, I surprisingly find out that I actually cannot pass the borders without declaring war. So, how border policy works now? I can pass borders until I open some tech or how it works? Also entering with my expansionist army didn’t triggered grievance to my opponent AI, which seems to be bug
