@Tag365Plus The EA App is still in beta and doesn't have all the functionality of Origin. It's getting updated and expanded as time goes by, but to be honest, I wouldn't expect it to ever fully support older games. It looks like EA isn't really focused on fixing issues with Sims 3 these days. So just keep using Origin for as long as it's available.
Has this issue been fixed? EA Desktop is supposed to replace EA Origin by the end of 2022 and possibly make the latter discontinued to the point that it can't be used in the future. I hope it is fixed so I can still use the Create a World tool.
@Tag365Plus I don't know whether this has been fixed, but I also haven't seen any other posts about it. If you'd like to test, please let me know how it goes. You can have both Origin and the EA App installed on your computer at the same time, although the App will uninstall Origin as it installs itself.
the in-game editing problem with CAW is still there, I also hope that EA will fix it so that it works normally with EA Desktop.
