I had this on Steam ages ago but recently got the game with the DLC on GoG. I'd like to transfer over my game save from Steam to GoG, any way to do this? I've found where the Steam game saves are but I can't find where they are on my GoG install.

Linux location of save files: .local/share/Victor Vran

Windows location of save files: C:/users/username/Application Data/Victor Vran

Copying the whole folder (including subfolders BugReport, Characters, logs, Save and DeveloperStorage.lua) between a Windows and a Linux installation worked for me.
