Multiple Technical Issues (The Sims 4)

Tlove202​  Please test a new save, for comparison's sake.  I'm not saying you need to abandon your old save, only that how a new save runs is useful information.

If the new save works fine, please move your main sims in your main save to a different lot, either a blank one or something EA-made, not a build from the Gallery or your own library.  You don't need to save your progress; this is also just for testing.

Please provide a dxdiag as well, for reference.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
