What's going on with this "1" profile?

[BytePride]

It seems like there's suddenly a user "1" who's on most of the top ten lists for the number grids. Their profile is https://numbergrids.puzzlebaron.com/profile.php?u=9127, where it lists the profile as having been started yesterday and having played a single puzzle, but they have records from years ago in the lists. Something's messed up in the database.

I believe this should now be fixed (but let me know if you still see it popping up).

There was a bug in the code that would in a rare occasion allow a registered user's profile to link up with "Guest" playing history - which would make the fastest-ever record held by a guest player (i.e. not logged in) show up as that player's own record time. Code has been updated to prevent this from happening again.

Thanks for catching this!
