okay good, at least I'm not crazy, but all your 'stuff' is gone--avatar, badges, name, location etc, in addition to your user name being different--also your profile page with your new username, all your stuff is gone--it's like it's not you but it is
kinda weird
maybe you need some admin help cuz I sure don't know how to get you back to being you
or maybe you want to start fresh? I can't know these things
