Hoping this Input will Be of Help...

I just realized that a lot of people are having issues with their games crashing, seeing the white screen of death, and now, more staggering and lag since this latest fix whereas before this latest fix our games were running so much smoother than ever before. It just recently started happening for me as well. 

I just thought that MAYBE these problems are more isolated and since we have had several new Expansions and so many, many more kits in recent months it could be helpful to narrow things down a bit. 

For starters, I will mention I did not use Mods/Custom Content after I recently repaired my game, removed my EA Game folder for the game to regenerate a new one. And began creating a new game from scratch.

My Game has the following: 

Expansions Packs: I most Packs up through For Rent. The latest five from Life After Death and on, I do not.

Game Packs: Own them all. 

Stuff Packs: Own them all, except Digital Deluxe.

Kits: I do NOT own the following: Dust the Bust, Street Carnival, Castle Estate, Goth Galore, Sweet Slumber Party, Comfy Gamer, Secret Sanctuary, Casanova Cave, Refined Living Room, Business Chic, Sleek Bathroom, Sweet Allure, Kitchen Clutter, Golden Years, Essential Glam, Grange Mudroom, Autumn Apparel, Modern Retreat, and Garden to Table.

While I realize the rest not mentioned can still contribute to some of these issues or of other issues, I am hoping that perhaps this might narrow down your ability to locate these issues a bit faster and easier.
