Original creations being credited to someone else

Another option that could help is to have a save-game that's just for your builds, one you use exclusively for your builds & sims.  If you never pop a d/l'd build or sim into that save-game, you should be good!

Thank you for replying. I will definitely try that. It also happens when I’m in CAS mode. I have created Sims from scratch and for some reason other people have either stolen it or a credits them as having been the creator. Even though I did NOT download any Sim and modify them.

How frustrating!  If it were me, I'd also clear my caches, just because, and I'd empty my trash folder, too.  And shut down & restart, 'cuz sometimes it seems to help!

Thank you so much. I will try that.

@AriAngel Another thing maybe you can try is to do all of your building & Sims creations on a fresh New Game save. I changed my Origin user name like 6 months ago and if I make any new lots or Sims from any of my old saves it still lists my old username on my new creations. If I use a new save then it lists my new username.

Thank you. That sounds like a great idea. I think I will try a new game before changing my Origin name.
