Okay so this tutorial is going to be complex. If a developer wants to turn this into a script he can.

As with any procedure that modifies files make sure you have a backup.

First you'll need the pak extractor by Norbyte:

Download it, extract it, run it.

Your saves are always stored here:
Documents/Larian Studios/Divinity Original Sin 2/PlayerProfiles/[YOUR ALIAS]/Savegames/[BUGGED SAVE FOLDER]/[BUGGED SAVE].lsv

It's this .lsv file we need to modify

From here, follow the instructions by the letter.

1:
Using Norbytes converter app, select the PAK /LSV Tools tab. You will see 2 fields. Package path and Destination. Use the ... button to the right of each to navigate to the relevant locations.

It will look something like this:


Click Extract Package

2:
Navigate to your [BUGGED SAVE] folder and delete the BUGGED SAVE.lsv and the .png - we no longer need them.

3:
Navigate to the converter app again and select LSX/LSB/LSF/LSJ Tools tab. Again we see an input and an output field.
You want to convert the globals.lsf into globals.lsx

It will look like this:


Click convert. There will now be a global.lsx sitting in your BUGGED SAVE folder. Navigate to it. Open it with a text editor. You will see that it is now an xml file.

It should look something like this:


4:
Now do a replace search for the following (CTRL+H = Replace Search)

Code:
						<node id="Permanent">


Make sure you copy paste that entire codeblock. The spacing is important.

You should see a line that looks like this:


Replace all instances of:
Code:
						<node id="Permanent">
							<attribute id="ID" value="WET" type="22" />


With:

Code:
						<node id="Temporary">
							<attribute id="ID" value="WET" type="22" />


and save the globals.lsx file.

5:
Navigate back to the converter app. We now need to convert the globals.lsx back into globals.lsf. Simply swap the input and output around. It should look like this:



Click convert.

6:
Navigate back to your BUGGED SAVE folder and delete globals.lsx - we don't need it now.

7: Navigate back to the converter app and select the PAK/LSV Tools tab again. If you have done everything as instructed you only need to click create package and the process is complete.

8:
Load your save. Any bugged permanent stats will be removed. Save your game once more and reload.

Hope this helps. Thanks for the save file Raze
