Yesterday I created the beginnings of a database for Trinity Psalter Hymnal, as far as I can tell the first 2018 publication in the database. I entered the first 25 or so hymns (texts and tunes). I actually created two such hymnal authorities, because the first one was incomplete (I was working on a cover image for it when I accidentally saved the authority (which meant of course that it would be inaccessible for a day or so); that was TPH2018. So then I created TPH2018a I think I called it, with the intention of moving its contents to TPH2018 after the latter became visible. I added TPH2018a to My Hymnals so I could keep working on it today, but now it's gone missing from My Hymnals. Who did this to me and/or to the database, and why?
