I made a post about it almost happening to me.
Once I was prompted to make a new character, I didnt. Just waited it out until I could get back in. I also connected to NA, and then went back to EU (where it happened), and it had worked.
My company member, who was also company owner, made a new character when it happened to him even earlier than me. Now he's still waiting for a DEV to come fix it.
Creating the character probably overwrites the previous one.
