DivinylsFan Noted regarding TS3 avatars.
Regarding the fallback default characters, it's not a deliberate choice that was in our hands, but pointing out the consequence to those that did make that choice is. Thanks for making me aware, I will be doing that next opportunity.
In the meantime, their team is working on addressing the bug so that we no longer see avatars reverting in the first place.
Meanwhile, our own team will continue to work towards a way to let users pick their own custom avatars in the future.
Lastly, while this forum is a community for all EA games and fans, Maxis did previously share some stats around the Simmers demographics. There was a discussion about it at the time here.
