Manage worlds and CAS Bug

Hi, after the new update date I have experienced more game crashes than ever. When trying to access the manage worlds or CAS my game immediately crashes and that is very disappointing because I was looking forward to trying out the new features in CAS. My game also crashes sometimes after spending hours loading in which is another issue I face when playing the sims then as soon as the home menu to the sims loads in it crashes. There is also a problem with the new expansion packs that I just purchased Life and Death and Adventure Awaits both of the worlds were showing up twice in the manage worlds before the new update. Please fix this as soon as possible. Thanks.
