Filename/folder permissions bug when updating lemma text

[susanodd]

For some reason, it's not possible to update the Lemma text to a different text that is not being used. The reason? The code is trying to move the image file which is stored under "glossimage/acronym/AN/annotation_NNN.png" to a new name. (Although it's using the Lemma annotation, not the gloss annotation.)

(This is local.)
