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

This mod for Mount and Bannerlord II: Bannerlord is an unofficial, fan-made solution to an issue that some players are experiencing in the game. The issue is that the main quest line ends and you have to start a new one, but you can’t because it’s the end of the game. So what’s happening is that you’re starting a new quest, but the quest line for the previous one is not ending. Its ending is still unknown, and it’s unknown when it’ll be resolved.

This problem has been fixed in the most recent update. So the only thing that’s left for this mod is to make the fix for the new update.
