I updated my HM to the .7125 build. After my DB was converted the the new version all my players notes have vanished. They are still stored in the _obsolete previous version of my DB but when I try to export them and import them to the new DB the process is almost instantaneous and no notes are transferred. The method I have used to do this is the following :
selected _obsolete database as the active one
went to back up tab and left all the config files selected
Selected Skip database option and exported.
Selected the new DB as active one
went to restore tab and restored DB with the option "skip database" selected.
