This is exactly why backups are a Dev’s best friend. Second only to copy and paste.

Future suggestion keep latest build backed up on USB or in a separate folder.  That said, did you check to see if you could restore to a previous session (some videos have an automatic save for up to the last 5 or 6 times of upstairs the code (and closing the program) meaning it could have Auto Backed up for you.

I really like tales of unity and would really hate for it to get shelved. I would hope that you try to salvage it and move on. It’s a good story and I like the characters. In fact I’ve grown quite attached to some of them. I know you’ve had issues with depression and I’m sure this didn’t help but know that there are people out there that really enjoy your work and support you. Sorry this happened. I hope things get better for you.

Oohh. I picked a bad time to re-playthrough to familiarize myself with the story again, lol.

Probably already decided but , personally, as much as I would like to see the reaction of everyone I think it's worth putting ToU on the backburner for now. That way your able to rebuild the script from the latest beta while working on P:J. It shows when your not entirely 'there' for whatever you're working on and I'd hate ToU to receive that sort of treatment because of something unfortunate as that happening.

While i can't magic your progress back, i recommend using repositories like git or mercurial to save intermediate versions to avoid things like this in the meantime.

I personally recommend mercurial (A.K.A. hg) with tortoisehg (a GUI), because it is a lot easier to use than git and way harder to fuck up.

If you are only using it so save your progress it is about 1-2 minutes daily of added work, but you have all your progress saved and can even go back to older immediate versions if something got messed up in between.

If you have questions or want some assistance/guidance setting that up, feel free to respond. I know that pain, buddy. (Though i only lost a few weeks worth of effort, not months)
