A free mod for Mount & Blade II: Bannerlord, by AlcoholV.

A mod to fix the bug with the character who was left with no location where the encyclopedia says he is. This mod is easy to use and simple to apply. It’s just a matter of changing the number in the day’s left to respawn to a number less than or equal to 0. It’s not a good idea to leave your hero in the prison for too long because he will eventually die and the game will be over.

You’ll need to check the number of days left to respawn every day because the mod doesn’t have a way of storing this information.
