Can anyone tell me what happened to my old account?

First, why can't you communicate other than with forum post with duplicate accounts? If you'd scroll the member list, you'd see your original username, which is the same except one letter than your new one: Abel.Emporia

I sent you a new password you can login with then change. This was done this afternoon.

Not remembering a password or username is not an excuse to create duplicate accounts. You can reach the staff by email or join Discord then tell us about your problem. There is also a password reset function that can be use on the login page.
