Is there a way to stop/delay independent/rebel factions abandoning their respected settlement(s). I am (after many years), currently playing early campaign as Crusader States, and on turn 8 all the independents/rebels decided to abandon their garrisoned settlement(s), leaving them free for the taking, when clearly it would have been better to sit tight.

If any of you guys could point me to the script/txt file etc. and possibly offer some advice on how to reduce/stop this behaviour I would be grateful. *CHEERS
