Hello:

Latest patch seems to have made it so that current save games do not work at all.

Thankfully, it seems though the files themselves are safely still in existence.

And new files can be made, so the game is not unplayable. Old saves might be dead.

Edit:

It might be, that save location was changed. Testing.

Edit:

So it was. For future reference to all users, save file location was changed. Transfer files to .\Bug Fables The Everlasting Sapling\Saves locations and it works normally.

Edit:

Copy still refers to old location.
