The team has been unable to reproduce this issue. If you are a PC player and this is occurring in single player or you are having the issue as the host in multiplayer, please let us know with a zipped save folder at email@example.com.
There are some players who have noticed that the game is no longer auto-saving their game when it is supposed to.
There have been some players who mentioned a workaround where they find a save that works and then deleted other saves until they maintained a save list of around 10. This issue is still being investigated.
Another method is to turn off the auto-save feature, reboot the game, and then turn the auto-save back on.
