@tsecniw_I had an issue with the duplicate copperdale world too, to quote a post I made on another site
“Open up origin, click on the sims 4 app and click on setting then select game properties, go to advanced launch options, and find the line called "command line arguments". (I also repaired the game through origin too)
Type in "-disablepacks:EP12" without quotes, EP12 is the HYS Expansion, to re-enable it, just remove EP12 after you're done.
I hope this helps!”
I just realize that forum ate some of that post too, when I was editing.
What’s missing is that you have to make an extra save file if you do this in case something goes wrong, you then boot up your game after you disable it, load the file that has the issue, save and quit, and then re-enable the pack
I hope that this makes sense
