"Save data saving failed..." Error, Can't Save on PC

Willie321

I play SN on an iMac and am enjoying the game tremendously. My father purchased the standalone game for his PC (fully updated Windows 10, laptop is less than 2 years old) from an on-line retailer, i.e., not Steam or Epic. We got the game to load and run by launching in Administrator mode, but when he tries to save a game, he gets the following error in a red SN error dialog:

Save data saving failed (Access to the path "C:/ProgramData/Unknown Worlds/Subnautica\TempSave\tmp171232\CellsCache\baked-batch-cells-9-18-7.bin" or "C\Program Files (x86)\Unknown



I assume that there is more to the message, but that is all that will fit in the dialog box. Note the changing direction of the slashes in the first path. I don't know if that's significant or useful. From what I've read about other users' save problems, my lead suspect is a permissions issue, but I have not had a chance to get back to the PC to investigate that in detail.

I have not seen an example of this specific Save problem in this or any other forum I've searched, though it now occurs to me that if someone was having a Save problem, even if they were using Steam or Epic, I might be able to adapt the solution to the regular Windows file structure that Dad's game is installed in.

Also when I get back in front of the PC, I will try to submit a report through the in-game feedback system, though I'm not sure if it will be able to capture the dialog because I don't know if F8 will be working while the dialog is showing.

Thanks in advance for any help you can provide.

Update: The in-game feedback system does not work with the dialog open. It may not have been operable at all, but I'm hazy, trying to remember from 5 days ago, and I didn't take notes. That's a whole other bunch of interface features to troubleshoot. Next time I'm on the system, I will try to submit feedback again, just without the dialog visible.

We tried using the Windows "Repair" installation option and also had to make sure that the game launches in Administrator mode, but it's working and saving properly.

Hi, I really liked this game. One day I played for 4 hours. And when it was the time to save, I had a really weird problem. I have a good computer and a good wifi.

But impossible to save. The button was already used. I could only leave the game without saving

SOLUTION: So, this glitch/bug happens when the temp data is wiped, which accidentally happened to me when i opened 2 instances of the game and then closed one.

Basically you need to copy the contents of whatever save you are playing eg. slot0000 into the folder C:\ProgramData\Unknown Worlds\Subnautica\TempSave\tmp288855 (the last number is different for everyone.)
