Re: Weird lag in build/buy mode and sometimes in Live Mode too

@JeanVW  How often does this happen?  Are there any patterns, for example that the same world(s) are affected, or only households with a high number of sims, or when you use a certain cheat?  Did this start happening before or after the June 3 patch?  Can you reproduce this reliably?

If you can reproduce, it would be useful to see whether it happens in a completely vanilla game.  Please test in a base game world (Willow Creek, Oasis Springs, Newcrest) in a clean folder.  Move your entire Sims 4 user data folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just start a new save and see whether the error reappears.  Let me know either way.

If you can't reproduce, that's fine, just tell me if there's a pattern to when it happens, even though it's sporadic.  I'd also like to see a dxdiag, in case anything jumps out.

When you say you "reinstalled your PC," do you mean that you reinstalled Windows, or reset the PC to factory settings, or something else?  There are a lot of different kinds of resets, and they're all a bit different in what they accomplish.
