Hurray!!!!!!!
Edit :
1)I have to admit that teutonic order knights and sergeants disband whenever you disband your lance troops and go to your manors where they randomly are recruited with other lance troops. It doesn't happen with other order troops.... I don't remember if I already posted that but I know that it hasn't been fixed....
It is an involuntary bug , I think, but it could be used to "change" partially the culture of a fief (or totally if you prefer). This could be implemented by being able to "invite in your manor troops of oltremare (if you are crusader) in the holy lands for example, that can slowly mix with your native troops when disbanded (if they survive that is), changing this way slowly, by the passing of time, the culture of your settlement .
2)When the player conquers a place, it is left with 0 garrison (if the AI does so there is always some troop left buck). with the new take over the garrison management system you can't leave behind some of the troops freed either because you suffer relation penalty and causes bugs like vanishing troops ...
I am the marshal of an empire in my current game but I will have to restart...
