Is it not supposed to call you a "terrarian" after you add your steam account?

After you add your Steam account, usually you get the "Steampunker" title. It's not working right no, you'll probably get it tomorrow. That's what Loki told me.

To connect your steam, you just sign up through steam correct?

You go to exterior accounts (or something like that) and that will give you the chance to sign into steam

Okay yup, I'm connected through my steam account because the only option given is to disassociate my steam account lol
