New account created and linked to facebook over existing one

We have a player that already created an account and linked it to facebook weeks ago.
Today after login with facebook he got a new account created, how is it possible ?

How can I prevent this to ever happen again and is there any way that he can still login with the first account instead of the newly created one?

Both accounts are linked to the same facebook account in Playfab now.

It looks like it already happened to someone else: https://community.playfab.com/questions/10846/bug-two-accounts-linked-with-the-same-facebook.html
I don't any repro and we have so many players I'm happy it's only the second time a user has this bug.

So everyone has the info: We took this offline and did a walkthrough of the code, using the values in the player accounts. What we've found is a rare corner case in which a player could, on a Facebook login to an existing account, wind up with a newly created account. We have a fix for this which is going through test now, and will be rolled out to the live service as soon as possible. If you find you have a user in this state, please be sure to send us the info on the player accounts in question without attempting any other changes - do not make any link or unlink calls to attempt to fix this manually. We can fix the player account links for you, but not if they've been altered further by those calls.

Hi @Brendan,

we have just registered the same issue on our title. A user created some months ago has logged in with Facebook and it has received a new account.

This bug has been fixed or it's still open?

I can provide additional information if you need it.

We rolled out the fix not long after my post above, and confirmed that it resolves the issue. Can you send me the Title ID of your game and the PlayFab IDs of the user accounts?
