We were able to reproduce the issue on one of our machines and have tracked the problem down to the igf圎M.exe process, which is part of Intel's graphics driver suite. We have noticed reports from various players stating that their games failed to save or load because of an issue with file system privileges. and let Steam guide you through the process. In the Steam menu navigate to Check for Video Driver Updates. If you use Steam, Steam can also help you search for the latest drivers. Here are the links to various graphics card drivers by manufacturer: Nvidia GeForce, and Intel HD Graphics. Usually updating your graphics card drivers or creating a profile for Subnautica in your graphics driver's control center helps.
