You were correct to state that the anchored objects you were using to create dropwords invoked the famous InDesign bug that stops its own vertical justification working.
Because InDesign’s vertical justification doesn’t work, V-Justify is not able to figure out what the justification “target” is in the pages of your document.
In version 1.6.0 there is an option to set the justification target to the bottom of the frame. For most pages in your document (except where there are footnotes) this fixes the issue.
For pages that include footnotes, it is still necessary to use the “As reported by InDesign’s own vertical justification” as the target, and then, because of the anchored objects, it won’t work. (This is one of the reasons is strongly recommend using Id-Extras’s DropWord script, which creates dropwords without resorting to anchored objects!)
