Songbook bugs

[Egon the Monkey]

I'm currently encountering two possibly related bugs on Alvin Anderson. One is that when I try and use /c songbook activate, I am told that the song I want to use isn't in my book, for several songs, quite often. Excelion's Excellent Introduction and the other UD songs seem to suffer from this most. The second is that I can activate certain songs regardless, through the menu within the book, but always get Hymn of the  Ymphian Jungle. The combat log, though, reports I have selected the song I chose.
