Lag after 1.103: Slow&Unresponsive Sims after update from December 5th

@BitterPearlCos Localthumbcache is a file in Electronic Arts > The Sims 4. If you use mods and CC, you need to know about this one because you need to delete it anytime you remove content from Mods.

What happens in a new save? For the new household, was it on a different lot? Ideally a lot that comes with the game, not one created by you or from the Gallery.

@dee15644 There can be a lot of causes of this other than mods and CC, but one that's come to my attention recently is a sudden huge excess of unhoused Sims. Have a look in Manage Households to see if a whole lot of new ones have generated, and delete them.

Other than that, common causes are -- depending on what your computer can handle -- lining up too many things in a row for the Sims to do, large households, and really stuffed large lots with lots of items that can be interacted with. Excess stuff in inventory can factor in too.

My sims are so slow and unresponsive the game is unplayable. I removed all mods and resetting the Sims doesn't work either. This has been since For Rent came out. It's so unplayable that I just don't play anymore and I've been playing the Sims since Sims 1 came out, I'm quite upset. I thought the latest update would fix it but no. I think I'mm going to try uninstalling For Rent and just have to play without it even though I spent money on it, is there any way of getting a refund? 

@ktbrennan484 When you removed the Mods folder, did you also delete the file called localthumbcache? And do you get the same lag in a new save, or in a different household on a small base game lot in your current save?
