Problem with loading my save after the update:

Lots of people have had problems with loading screens. One possible cause is the Off The Grid lot trait/challenge. I think the recommended workaround, if that's the cause, is to open the lot from the world view using Build mode and remove the lot trait. To do this, you'll have to use Load Game rather than Resume Game.

For other possible causes, see the master thread at EA Answers. [MASTER THREAD] Crashing and Endless Loading
