Placing walls extremely laggy after new patch

@beccas24  There's always some trial and error when moving content from an old Sims 4 folder to a new one.  In your position, I'd move over one save and test it, just to see whether you get any more lag.  It's possible the problem is from the saves themselves, but it's also possible the issue is something else in your old folder, and you won't know until you test.

By the way, the Dell Alienware Command Center software on your computer is crashing.  You already have the newest version, so there's nothing to update.  If you don't notice any issues, you can probably ignore it, but if you do see slowdowns either in-game or in general, try shutting down the software.  You should be able to find it in the background tasks category of the Task Manager.
