During the last update, was there recent changes to the Automaton?

I've been increasingly upset over how often my Automaton will cast Poison over a cure VI when I'm at 25% health. This is with Light Maneuvers up and Damage Gauge attached.

Yesterday I died 3 separate occasions because the Automaton refused to cast 1 cure spell, regardless my health. He's even casting Dia II over haste. I've been needing to ask my WHM's to cast haste on me because my Automaton just stopped.
