what do you mean?
loaded old save, finished it all, zero problems...did you forget to update walki mod or something?
Have the same issue. Not using any mods, but the game is erroring out stating that the script has changed and couldn't find a point to stop rolling back. My usual method of getting around this by loading an older autosave isn't working.
I'm guessing the f95 incest patch that's been automatically included is interfering with the save. Normally, I stop playing games when things like this happens after a long run, but it's short enough for me to restart.
