Can't Save
 

After losing my save game yesterday while playing, I have just restarted the game from the start and found that I can't save. At all.

Is anyone else having this issue and how do I fix it?

I'm playing with Wolves of Steel mod pack, and nothing else.

And I've turned off my sync to cloud saving due to losing my entire campaign save.

Hi iowa
It would appear things have not gone right for you from the start.
Make sure you follow the new TWOS instructions correctly.
You must make a game save in the bunker and use that game save to start your Mission.
Try starting a New Campaign and see if things are now working ok, if not I would suggest re-installing after using a registry cleaner.
TWOS is 100% working with no problems so it is going to be down to you or your system, not TWOS.
