Campaign armies not moving

[Ponthos]

I'm playing a Denmark campaign, in Retrofit mod. After 40 turns, I notice that most of the AI factions have large armies just outside of some of their settlements, that are constantly being reforced but do not move. Then I notice many rebel cities, that should have been captured by now, like Inverness. And Scotland has an large army, just outside Eddinburg, that does not move.

Also, a medium sized Polish army besieged and tried to assault a rebel castle, next to my lands, aroud turn 10. However they were defeated, and retreated to my lands. 30 turns have passed, that Polish army is still in the same place, and the Polish haven't attempted to take that castle by assault again.

Do I have some kind of AI bug with this mod? Also is it possible that other mods and the vanilla game, also have this bug, because

because I also have AI problems with Third Age

AI in vanilla is bugged and Retrofit uses it.

Third Age, contact their forum.
