My sister and I both play with all 11 expansion packs plus High End Loft Stuff. Neither of us run any programs in the background while playing the Sims 3 and we play on all worlds that come with each expansion.

Also, I've attempted to create a new folder, however, for some reason, it says there is an error and that Origin needs to be installed.
As I was playing, for some reason, the loading times are much longer, and then my game froze at one point.
