Created account, name taken, still created?

[Nordlys 1,425]

So i created an account and when i pressed the link to verify from my email, i got a message that the name was taken.

Now i cant create more accounts on that email because i have 5 accounts already - one of them which i dont have, because the name was taken. How is this possible? Please fix.
