7169ebd79916e3f1 If you play this same save again, does the same thing happen? You can End Task through the Task Manager after about five minutes if it hasn't saved by then. Try "save as" if the normal "save" doesn't work.
If "save as" doesn't help, try saving with a different, previously-unplayed household active. (Use "save as" again to avoid overwriting your original save and its progress.) If that doesn't help either, start a new save and see whether you can save your progress. If you can, restart your computer and try again, just to be on the safe side.
Let me know what you find, and we can go from there.
