No everything but 2 (oldest 2 days ago). I'm guessing I lost everything, then added 2 bookmarks without realizing bookmarks were gone. I am not shutting out other explanations tho. Maybe nothing wrong with amethyst. (Running v0.91, but couldn't downgrade to v0.90.6, so still looking.) 

 Ohh yes. Most definitely the list got deleted at some point or the relay that had it got busy, was offline and didn't send on time. Then Amethyst started a new one when you added a bookmark.  

 Okay, right, so that's how the mechanism works. That makes sense. Good to know. 

 I have a bit of difficulty believing that the bookmarks simply disappeared. Is this common?
It's just one of a few lists, so it could have been deleted from the server, but there has never been any delay or issue at all. 

 The same happened to me, all the bookmarks(private + public) are gone. So I assume there is no way of getting them back?
