I have seen many posts on the Sims 3 Forums about crashing while traveling to other places in World Adventures, but my game crashes maybe on day 1 or 2 of my vacation in Champs Les Sims.
I just recently bought World Adventures with Supernatural. I have Late Night, Ambitions, Generations, and Pets as well. So far in World Adventures, I have traveled to China 2 times and I am currently in France. I have yet to go to Egypt. But in France, I have just a couple sims with me, both are completing adventures. Right now in the game, it is night, and I am having the two sims sleep. While they are sleeping, the game completely crashes and I get a popup saying the Sims 3 has stopped working. Sometimes the game lasts long enough for the sims to get rested and wake up, but it crashes shortly after.
I have a well built desktop with plenty of memory space, and a good graphics card to go along with it. I run it on vista (64x). I don't think it is an error with my computer since I have not had a problem with it running sims before traveling to France in WA.
I also just now installed the Sims 3 Crash Log Analyzer, but I am not sure how to use it at all. And I just used the Sims 3 Patch Downloader to download the most recent patches. But still no luck.
