I had the "Can't save" problem before and changing permissions on the users/documents/mygames/Fallout4 folder to full access for everyone fixed it. This time I can't figure it out.
The last time I played was Jan 30. On Feb 1 there was an update to Fallout 4, and now I can't save any more. It may not be the update that changed something, but something is different. I am currently running Fallout 4 version 1.2.47.0.
I have checked the folder permissions and everything is still set to full access. I renamed the users/documents/mygames/Fallout4 folder to something else and re-started the game. It recreated the folder identical to the renamed folder (I guess it is getting all the saves from the cloud?), only without the 3 .ini files (Fallout4.ini, Fallout4Custom.ini, and Fallout4Prefs.ini). Still same problem - cannot save game.
Any ideas of what it is this time?
