Noticed this silly AI behavior, I conquer a city, and the AI just harmlessly puts a small stack in front of my city, just chugging along, and it's free XP for me.
The AI needs to reconfigure routes and take into account threats (and probably amplify player threats) when a city is captured, and maybe if an outpost is razed.
This behavior seems to be a holdover from GC2 as well.
