I’ve been playing for a while, now, using my Steam login.
Just now I was not given the option to play using my steam profile, and had to use the Gaijinnet profile or whatever.
It came up with the same account as always (same name anyways) except EVERYTHING had been wiped. NO ships, no progress, no credits, no corp. It was as though I had logged in for the first time again.
It even started to pay the tutorial.
I was even playing just earlier today and everything was fine.
