Awesome! Thanks a ton! 

I just wanted to say I noticed this was marked as experimental and I can vouch for it working. I backed up my game and followed the instructions and successfully reset China. I was a very happy camper.

So thank you for making my life just a teensy bit better! 

Sigh... okay, sorry, I was frustrated and I posted without saying anything helpful, I realize that.

I'm glad that the suggested mod worked for somebody else but it doesn't appear to be up to date with the most recent patch and is not working for me. Are you running a game patched up to 1.47 and this mod is still working for you?
Anyway, I did have a thought (just the one), I have twallen's error trap installed, and though I don't necessarily understand exactly what it does, I do know that I lose opportunities related to sims when errortrap mentions them. I will get a message saying that I can't complete my opportunity because the sim related to my opportunity is no longer around, which is weird because they definitely are. Is it possible that sims are being reset by error trap, and that maybe when they are reset, this mucks up the gifts they have sent out? If what Idle said is true, and this mail issue is caused by sims being deleted or leaving, maybe it could be caused by a sim being reset, too. If everyone else is using errortrap, or if perhaps there is something similar built into awesomemod, maybe this is the source of the problem and can be disabled.

Thoughts?

I've been having the same problem and I just tried running my game with that mod and my game crashed within five seconds of starting up! I'm inches away from rage-quitting my game!
