Yup, I think that’s happening to lots of folks, including me. I’d give it a day or two for the servers to catch up, since it seems there’s a backlog.

Would this affect folks trying to register new accounts? I just tried registering but haven't received the code in my email.

You can't actually change the sex of the body, unfortunately! If you pick female, you're stuck with boobs. I usually do a male body with a vagina. It's kinda funny honestly. You can add or remove a dick/vagina, but not boobs!
