Hello, I am Mafe. I will make this short tutorial on how to unstuck you save in case you save got softlocked in some point.

First of all, you need an external tool, called Save Editor. To open the save editor, you need the last Java version.

Get the Save Editor here (always use the last release): https://github.com/robojumper/DarkestDungeonSaveEditor/releases

Get Java here: https://www.java.com/es/download/

After you installed Java, and after you got the last Save Editor .RAR, extract the content of it on any place (recommended: Make a new folder for it called "DD Save editor") and after the extraction is done, open the .JAR archive inside.

When you open the program, you will need to set you save directorty location. If you use Steam, it is the following:
C:\Program Files (x86)\Steam\userdata(your profile number)\262060\remote(profile)

Your profile number will be a string of numbers; there should only be one folder in the userdata directory unless you have multiple Steam accounts on your computer. The profiles run from profile_0 (top slot) to profile_8 (bottom slot), so make sure to load the one that actually corresponds to the correct save. Go to the "persist.game.json" tab, and look for something along the lines of
"inraid" : true,
"raiddungeon" : "weald",

Where "raiddungeon" will be the dungeon you're in. Change it to:
"inraid" : false,
"raiddungeon" : "none",

To set yourself back to the Hamlet and fix broken saves.
