Desolate: Upcoming Hotfix
Hello Volunteers!
We know that under specific scenarios, game clients and servers may lose their progress. We're working on a solution. An update with a bugfix will be released soon.

In order not to lose progress, after leaving the server or ending a session do not restart the session from the main menu, but rather restart your game and then your session.
If you have this issue you can contact @Niko on the game's Discord and he will help you to resolve the issue manually. The progress will be restored together with the patch or a little after, so that it doesn't corrupt or get erased again.
