i've not had that problem. i had some glitches when i restored from backup on beta 1, so i started again from clean install and no restoring at all. i think you might have hit the nail on the head with your last line, there's a very valid reason why the notes said not to restore from backup and install totally as fresh and you situation epitomises it.
yea one suggestion i got from someone was to completely restore it clean, which i really dont want to do because ill lose everything
