Guardian's Hammer of Wisdom no longer respecting Snap Ground Target to Current Target

[Furyus.2183]

I frequently run with Autotargeting and Snap Ground Target to Current Target checked/enabled. I frequently use Hammer of Wisdom on my Guardian as my combo finisher. Recently, i.e. within the last day or so, Hammer of Wisdom ceased respecting Snap Ground Target to Current Target. Instead, it now targets/lands wherever my cursor happens to be pointing at the time. I have checked other ground-targeted spells (e.g. Purging Flames); they are working as expected (they snap to my current target).
