Saves files not loading or completely gone

[Simulated Twig]

I have played for about 10 hours in a save file, but after quitting and re-loading the game my save files are gone from the load game list. They are still in the Little Big Workshop folder on my PC, but in game they are nowhere to be found.
When i try to continue the game even after a couple hours, i get an error that the game was unable to upgrade save to latest version.

This is happening when I am playing the game only a few hours after quitting in the same day.
Had to restart twice now and getting pretty frustrated.

Hi SuperMuench!

Sorry to hear that you are experiencing issues with our game, we haven't received any similar reports like this.

My initital thought goes to steam cloud sync is weiring out or something, but of course that is only speculation.

Do you remember what you did, only playing normal, quitting to main menu or desktop? booting up the game again and the saves are visually gone, but exists on the drive?

Perhaps there are some bug inside your savefile, could be a lead.

Could you please take your time and send us your save and logfile to [e-mail]

Please include a weblink to the original thread in the mail.
