Pam, so sorry to hear, all that work on mixology and now you have to do it all over again. Wish you a lot of patience.
I had a smaller tech issue, I had 3 deaths on one party so game gave me some bugs, again map tags were gone, none came to another 2 parties legendary host were hosting, and finaly it froze while processing when Sim was added to family by marriage. It was processing for good 15 minutes until I gave up (I managed to make and drink a cup of coffee in meantime). I lost only 1 Sim day, and game looks fine now, but still not shore what to do when things like this happen but to quit game (I had to use task manager to turn it of).
