No, but I was playing the game around that time or even older. The game was having problem with save files from old version to new version. Now I just need to know if it's still a thing. I'm not fancy playing all over again.
Save files saved to disk from 0.8.3 works in 0.8.3.9.
Save files saved to disk from 0.8.2.3 needs to be patched to 0.8.3 to work in 0.8.3.9. The use of the general debug option too in 0.8.3 to make sure you can pick at least some of the character creation traits the 0.8.3 rework made available to all players. You are probably not going to have as much traits but if you want to preserve some uncapped stat gains from the old save file, sure.
Save files saved to disk from 0.8.0 or something probably needs to be loaded into 0.8.2.3, saved to disk, patched to 0.8.3 to work in 0.8.3.9.
