When going back to the main menu after reading, sometimes my Kobo Aura HD (unmodded) fails to save the current reading position. When it happens, it seems to happen for every book. Rebooting the Kobo always fixes the issue.
I've noticed this more and more recently, although I'm not sure if it's the recent firmware updates or the age of my Kobo.
I had Windows run an error check on the drive but it came up clean.
Does anybody else have this issue, or any solutions to it?
