Is it possible that staged users are deleted automatically after a while, if they don’t reply? This seems to have happened on my site with a handful of staged users from over a month ago - maybe 15 of them. I have been using staged users as part of my effort to use discourse as a ticket system, but now I am finding that the people I was writing to are gone and the messages are just to myself and there is no sign of the staged user, in the message or in the user list. I can confirm in mandrill that the email notifications were sent to the email address of the staged user.
Any insights much appreciated.
