There a chat user who has no valid parent user. It is indicated that his chat account is associated to a Maths.SE account, which does not appear to exist. The user was still able to chat.

Is it normal? If it's a bug, could someone look into it?

Edit: if you browse the Google cache for users named Skullpatrol, it turns out a single series of associated accounts. The user is now named Rob. I don't know what went wrong, maybe an account merge or something like that, but it needs someone from staff looking into it with some superpowers.

I also tried to update the parent user of the chat account to this "Rob" profile, but the interface goes all buggy on me (works for other users, fails only for this one):

Well, it's normal in the sense that it's the typical behaviour for chat when a (all?) parent users are deleted, but I don't know if it's necessarily the expected behaviour. Also, if the user was still able to talk after having their parent user deleted (and after chat synced), that's probably not a good thing in either case. – Tim Stone Mar 25 '12 at 14:56

This happened because this user's original user was deleted, and they created a new one (22862, the one you found), which was then associated with the other accounts the user already had previously. I have fixed up the particular account.

This kind of issue used to be a pretty unsolvable problem (at least as far as automatic handling goes) back when chat was created, but with our not-so-recent-anymore user account backend improvements, this should actually be doable now. So I guess this is a wakeup-call to start improving :)

Thanks for the detective work, that really helped.

Seems there's another (obnoxious) case. – Tim Stone Apr 14 '12 at 19:46
Does this still happen when deleting parent accounts? It seems a bit awkward for moderation purposes. – Jefromi Apr 20 at 18:02
