We’re experiencing the same pesky issue, which coincides with an update to 2.6.1. We have a number of pages that we publish peoples’ profiles to, and each profile contains a picture. While I haven’t noticed the number of profiles/pictures after which contents disappear, a user will add a profile, click save, and contents of that page are gone… THANK GOODNESS for the page revisions, the discovery of which has prompted a mad frenzy of saving after each and every profile. One thing I have noticed though, is that just prior to each time the page loss occurs, is an inexplicable [Autosave] by Userxxx entry in the page revisions. The weird thing is that this user isn’t the one who last updated the page prior to the disappearance, and often isn’t even logged in, or on the web at the time.
