You should reset all the variables set on the player's ID after everything has been saved or before you load anything. Also, you should check whether the player who is disconnecting is logged in or spawned. Otherwise you get faulty data.

And if you actually have a server with +70 players, then why don't you consider using an actual hashing algorithm? udb_hash is easy to crack and thus not secure at all.
