Re: Build mode causing crashes

@CrowleysAngels07  Even though it's mostly suggested for Mac users, try enabling vertical sync within the graphics options and see whether it helps.  You'll need to be in fullscreen mode for the setting to be available.

If that doesn't make a difference, please move your entire Sims 4 user folder out of Documents\Electronic Arts and onto your desktop.  When you launch the game, a clean folder will spawn with no content.  Don't add anything to that folder; just test Build mode and see how it runs.

If you get another crash, please run a dxdiag and attach it to a post.
