I've been frustrated by the lack of a proper saved game function in this game. I thought it was a fluke the first time I lost progress, so I took to frequently backing up the PlayerProfile.dat file to ensure I would not lose progress. Nevertheless, again I come back today and have lost a bunch of progress for no apparent reason and have to replay puzzles I just solved yesterday. Is this a known issue?

Also strange, it created two profile folders for me, The Talos Principle\UserData\46988348122871883 and another one The Talos Principle\UserData\0

It looks like the game might be getting confused.

Oh, I see...

If I have GOG Galaxy running, it finds my profile number and uses that as the folder name.

If GOG Galaxy isn't running, then it puts 0 as the folder name.

Doesn't tell the user. Doesn't let them choose. What a design decision...

Jeez. I hope this helps the next guy.

Same here.

Someone else ?

It’s still very boring ! I find scattered testimonials on various forums but never any solution and above all, it is NOT a recurring subject ! Do the developers only have the info?

It’s a pity, I really liked the game and, for a saving problem I will never know what is at the top of the tower. : -(

How to reach Croteam? Is there a "Bug Report" somewhere?

The second time I ran the game, I was surprised that all my progress of my first time was lost and no way to recover. I repeated like 5 hours of my first time. Then, after I had made a considerable progress, maybe half of the game, after, let's say 10-15 hours and 15 achievements, today again all my progress is lost. That's a bummer. At this point I don't know if I want to start again or just uninstall the game.

EDIT: No backup of my previous playthroughs appear. Just "start new game" and that's it.
