That's going to be a game bug, so we won't be able to fix it for you here.

Please make a new thread in Bug Reports and attach that save there (no need for the other files). QA will look into it and raise it with the developers, although not until next year at this point.

Just put that save aside and try it as you see new patches come out.

Sorry for that problem!
