I'm so sorry!
Once it's fixed, could I tempt you into making an expendable savefile, that you use for testing out new packs? In case this is helpful, I have a 'gold-digger/black-widow' sim that I use for this purpose. (It's actually pretty funny; the gallery has sim versions of many politicians, so...yeah...she marries and murders the ones I'm mad at! --don't worry, in real life I'm decidedly nonviolent. I do find it funny when a particular sim-politician-ghost stomps around steaming mad 'cuz he's still jealous about who she's cavorting with now!) However, long-term, that gameplay doesn't keep my interest, so it's perfect for use when I'm waiting for bugs to be patched.
Good luck on the game repair! Hope you can find some interesting threads to distract you, or some good music to listen to!
