I have recently downloaded the update and now have a bug which I will try my best to describe. I have the game installed on an hdd (G:), the save file is in my documents folder which is on a different hdd (E:). Finally, I have Windows installed on an M.2 (C:).
I keep running into a problem where I play for about 5 minutes (on a save I had previously been playing on before the update), and then when it attempts to auto-save or I manually do it, it informs me that the drive cannot be found and so cannot save - it is referring to drive (E:). I am then unable to access my drive (it doesn’t show up in file explorer and all data installed on it becomes unavailable - inc. my desktop etc…), although it is still registering that it is there in partition manager but not correctly. To fix it, sometimes restarting my PC works, otherwise I have to unplug and then plug the drive back in and it then works. There are no errors coming up on the drive and it is interesting that it is the drive with the save on it that is having issues - not the one with the game installed on it which is operating completely fine. The (E:) drive has plenty of space available and I have never had an issue with it before, and it only happens when I am playing the game. I believe I am able to save successfully for a short while when I first launch the game, as I can hit save and it doesn’t produce an error and my drive is fine.
Happy to send any error logs or any other details if you want them and hope this is useful.
