I just went to look in one of my Leo files and I just found that I've lost all of my content under the@file nodes. The only hint I have is:
restoreDescendantAttributes: can not find VNode (expanded): gnx = alsoeric.20170209115147.1, tref: alsoeric.20170209115147.1
I don't know if this is related or a red herring. The files I lost the content of were an original and a duplicate. I remember working with a duplicate and it seemed to be okay but now it's data is also lost.
I'm rooting through my backups now to try and recover the original file. I'll let folks know what I find when I find it
I think I've seen something like this when I forget to save a Leo file. I'm going to go look through my backups and hopefully be able to recover.
