I was replying to AI disbanding troops when they get diplo-vassalized and asNo I don't believe that's what it is.
My vassals are fielding fewer troops as they get bigger, and the game gets later.
In other words they are saving money for something.
I'm talking about like Prussia, Bohemia, Bavaria etc.
150 development 9 Province Prussia is fielding 2000 troops right now, 34 development Siena with 1 province is fielding 6000.
I have a suspicious feeling they are saving up for higher level forts.
Seraphithan added forgot about the force limit difference too.
