Game Crashing in Build Mode

Aubyn06​  Sorry for the late reply.  If you'd still like help, please let me know whether this happens in a new save too, and if not, on a different lot within your main save.

If the new save is affected too, please provide a dxdiag.  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.
