if you were using an out of date mod for your save file then the content ends at whatever patch the mod was made for so try putting sancho save fix in game folder
This is made only for modded saves using Sancho mods to work unmodded, won't work for other author mods. For what I know this game have only scrappy multi mod available and isn't updated yet. If
Xeros30 used that scrappy mod in version 3.1 and the saves won't work then has to wait for scrappy to update it. I just downloaded the game, after install I'll check if the saves work since I was using scrappy mod too.
Edit: The last saves of version 3.1 modded saves with scrappy mod work in the unmodded version 3.2, they just rollback a little but they work anyway and I could see a bit of the new 3.2 content.
Xeros30 did you made a fresh unmodded install of version 3.2 or you used the update only BoB69 posted a while back on top of the old installation? If the latter then maybe that is the problem you facing, using 3.2 version with an outdated mod. Download the full game, it is safer and the saves work and then you can see the new content.
