Hi,
I'd need some more information about your problem:
- Current game version and platform
- was it updated, if so from which version?
- did you delete the previous version before updating
- or did you copy the files from the new version archive to your game directory with older version
- is it happening for only this one save file?
- What happens when you load auto save or save from any other slot
Please try to answer the above and provide as much details as possible.
Cheers
